Use RDW to solve the following problems.
\nQuestion 1.
\nLauren ran a marathon and finished 1 hour 15 minutes after Amy, who had a time of 2 hours 20 minutes. Cassie finished 35 minutes after Lauren. How long did it take Cassie to run the marathon?
\nAnswer:
\nThe time taken by Amy to complete the run = 2 hours 20 minutes
\nThe time taken by Lauren is 1 hour 15 minutes more
\nWhich means, 2 hours 20 minutes + 1 hour 15 minutes = 3 hours 35 minutes
\nThe time taken by Cassie to finish the run is 35 minutes more than Lauren
\nWhich means, 3 hours 35 minutes + 35 minutes
\n= 3 hours 70 minutes
\nIt is also written as 4 hours 10 minutes
\nTherefore, Cassie took 4 hours 10 minutes to run the marathon.<\/p>\n
Question 2.
\nChef Joe has 8 lb 4 oz of ground beef in his freezer. This is \\(\\frac{1}{3}\\) of the amount needed to make the number of burgers he planned for a party. If he uses 4 oz of beef for each burger, how many burgers is he planning to make?
\nAnswer:
\nThe amount of beef Chef Joe has in his freezer = 8 lb 4 oz
\nGiven that, 1\/3 of the amount is needed to make the number of burgers
\nNow, 3 x ( 8 lb 4 oz )
\n= 24 lb 12 oz
\n24 lb is also written as 384 ounces
\nSo, 384 ounces + 12 ounces = 396 ounces
\nIf he uses 4 oz of beef for each burger
\nThe number of burgers he is planning to make =
\n396 \/4\u00a0 = 99
\nTherefore, chef Joe is planning to make 99 burgers.<\/p>\n
Question 3.
\nSarah read for 1 hour 17 minutes each day for 6 days. If she took 3 minutes to read each page, how many pages did she read in 6 days?
\nAnswer:
\nGiven,
\nThe time each day Sarah read for 6 days = 1 hour 17 minutes
\n1 hour 17 minutes = 77 minutes
\n77 minutes\u00a0 x 6 days = 462 minutes
\nIf she took 3 minutes to read each page , the number of pages she can read in 6 days =
\n462 \/ 3 = 154
\nIn 6 days she can read 154 pages.<\/p>\n
Question 4.
\nGrades 3, 4, and 5 have their annual field day together. Each grade level is given 16 gallons of water. If there are a total of 350 students, will there be enough water for each student to have 2 cups?
\nAnswer:
\nWe know that, 1 gallon = 16 cups
\n16 x 3 = 48 gallons
\nNow, 48 gallons in cups =
\n48 x 16 = 768 cups
\nWe have 768 cups of water
\nTotal number of students = 350
\nNow, 350 x 2 = 700 cups
\nTherefore, therefore is enough water for each student to have 2 cups.<\/p>\n
Use RDW to solve the following problem.
\nJudy spent 1 hour 15 minutes less than Sandy exercising last week. Sandy spent 50 minutes less than Mary, who spent 3 hours at the gym. How long did Judy spend exercising?
\nAnswer:
\nGiven,
\nThe time spend by Mary at the gym = 3 hours
\nThe time Sandy spend at the gym is 50 minutes less than Mary
\nWhich means,
\n3 hours – 50 minutes
\n= 2 hours 10 minutes
\nThe time Judy spent at the gym is 1 hour 15 minutes less than Sandy
\nWhich means, 2 hours 10 minutes – 1 hour 15 minutes
\n= 55 minutes
\nTherefore, Judy spent 55 minutes for exercising.<\/p>\n
Use RDW to solve the following problems.
\nQuestion 1.
\nAshley ran a marathon and finished 1 hour 40 minutes after P.J., who had a time of 2 hours 15 minutes. Kerry finished 12 minutes before Ashley. How long did it take Kerry to run the marathon?
\nAnswer:
\nThe time taken for p.j. to complete his run = 2 hours 15 minutes
\nThe time taken for Ashley to finish his run is 1 hour 40 minutes after p.j.
\nWhich means, 2 hours 15 minutes + 1 hour 40 minutes = 3 hours 55 minutes
\nThe time taken for Kerry to finish his run is 12 minutes before Ashley
\nWhich means,
\n3 hours 55 minutes – 12 minutes = 3 hours 43 minutes
\nTherefore, Kerry took 3 hours 43 minutes to run the marathon.<\/p>\n
Question 2.
\nMr. Foote\u2019s deck is 12 ft 6 in wide. Its length is twice the width plus 3 more inches. How long is the deck?
\nAnswer:
\nGiven,
\nThe wide of deck = 12 feet 6 in
\nAlso given, The length is twice the width plus 3 more inches
\nSo, 12 feet 6 inches + 12 feet 6 inches + 3 inches
\n= 24 feet 15 inches
\nWe, know that, 1 feet = 12 inches
\nTherefore, the deck is 25 feet 3 inches long.<\/p>\n
Question 3.
\nMrs. Lorentz bought 12 pounds 8 ounces of sugar. This is \\(\\frac{1}{4}\\) of the sugar she will use to make sugar cookies in her bakery this week. If she uses 10 ounces of sugar for each batch of sugar cookies, how many batches of sugar cookies will she make in a week?
\nAnswer:
\nGiven,
\nThe amount of sugar Mrs. Lorentz bought = 12 pounds 8 ounces
\nWe know that, 1 pound = 16 ounces
\n12 pounds 8 ounces = 200 ounces
\nIf she uses 10 ounces of sugar
\nThe number of batches of sugar cookies she will make in a week
\n= 200 \/ 10 = 20
\nTherefore, she will make 20 batches of cookies.<\/p>\n
Question 4.
\nBeth Ann practiced piano for 1 hour 5 minutes each day for 1 week. She had 5 songs to practice and spent the same amount of time practicing each song. How long did she practice each song during the week?
\nAnswer:
\nGiven that,
\nThe time Beth Ann spent to practice piano for 1 week = 1 hour 5 minutes
\nTotal number of songs = 5
\n1 hour 5 minutes = 65 minutes
\n65 minutes x 7 days = 455 minutes
\nNow, 455 \/ 5 = 91
\nTherefore, Beth Ann practiced each song for 91 minutes.<\/p>\n
Question 5.
\nThe concession stand has 18 gallons of punch. If there are a total of 240 students who want to purchase 1 cup of punch each, will there be enough punch for everyone?
\nAnswer:
\nTotal number of students = 240
\nWe know that,
\n1 gallon = 4 quart = 8 pints = 16 cups
\n1 pint = 2 cups
\nNow,
\n240 x 2 = 480 cups
\nTherefore, There will be enough punch for everyone.<\/p>\n","protected":false},"excerpt":{"rendered":"
