We know the Speed of the Object is nothing but the distance traveled by the object in unit time.<\/p>\n

Formula to find out Speed is given by Speed = Distance\/Time<\/p>\n

Word Problems on Calculating Speed<\/h2>\n

1.\u00a0 A man walks 25 km in 6 hours. Find the speed of the man?<\/p>\n

Solution:
\nDistance traveled = 25 km
\nTime taken to travel = 6 hours
\nSpeed of Man = Distance traveled\/Time taken
\n= 25km\/6hr
\n= 4.16 km\/hr
\nTherefore, a man travels at a speed of 4.16 km\/hr<\/p>\n

2. A car covers a distance of 420 m in 1 minute whereas a train covers 70 km in 30 minutes. Find the ratio of their speeds?<\/p>\n

Solution:
\nSpeed of the Car = Distance Traveled\/Time Taken
\n= 420m\/60 sec
\n= 7 m\/sec<\/p>\n

Speed of the Train = Distance Traveled\/Time Taken
\n= 70 km\/1\/2 hr
\n= 140 km\/hr<\/p>\n

To convert it into m\/sec multiply with 5\/18
\n= 140*5\/18
\n= 38.8 m\/sec
\n= 39 m\/sec (Approx)
\nRatio of Speeds = 7:39<\/p>\n

3. A car moves from A to B at a speed of 70 km\/hr and comes back from B to A at a speed of 40 km\/hr. Find its average speed during the journey?<\/p>\n

Solution:
\nSince the distance traveled is the same the Average Speed= (x+y)\/2 where x, y are two different speeds
\nSubstitute the Speeds in the given formula
\nAverage Speed = (70+40)\/2
\n= 110\/2
\n= 55 km\/hr
\nThe Average Speed of the Car is 55 km\/hr<\/p>\n

4. A bus covers a certain distance in 45 minutes if it runs at a speed of 50 km\/hr. What must be the speed of the bus in order to reduce the time of journey by 20 minutes?<\/p>\n

Solution:
\nSpeed = Distance\/Time
\n50 = x\/3\/4
\n50 = 4x\/3
\n4x = 150
\nx = 150\/4
\n= 37.5 km<\/p>\n

Now by applying the same formula we can find the speed<\/p>\n

Now, time = 40 mins or 0.66 hr since the journey is reduced by 20 mins<\/p>\n

S = Distance\/Time
\n= 37.5\/0.66
\n= 56.81 km\/hr<\/p>\n

5. Ram traveled 200 km in 3 hours by train and then traveled 140 km in 3 hours by car and 5 km in 1\/2 hour by cycle. What is the average speed during the whole journey?<\/p>\n

Solution:
\nDistance traveled by Train is 200 km in 3 hours
\nDistance Traveled by Car is 140 km in 3 hours
\nDistance Traveled by Cycle is 5 km in 1\/2 hour
\nAverage Speed = Total Distance\/Total Time
\n= (200+140+5)\/(3+3+1\/2)
\n= 345\/6 1\/2
\n= 345\/(13\/2)”
\n= 345*2\/13
\n= 53.07 km\/hr<\/p>\n

6. A train covers 150 km in 3 hours. Find its speed?<\/p>\n

Solution:
\nSpeed = Distance\/Time
\n= 150 km\/3 hr
\n= 50 km\/hr
\nTherefore, Speed of the Train is 50 km\/hr.<\/p>\n
