At what time did your friend start juggling?<br \/>\nAnswer: 10:57\u00a0 A.M<\/p>\n<p>Explanation:<br \/>\nGiven in the question that Friend practices juggling for the same amount of time as you.<br \/>\nSo that you started practice at 10:40 A.M to 11:04 A.M<br \/>\nSo the amount of time you practiced subtract from end time to start time we get 11:04-10:40= 24 minutes<br \/>\nso your friend\u00a0 stops at 11:21 A.M<br \/>\nHence to find your friend and started at\u00a0 is subtract 24 minutes of your practice time in to end time of your friend that is 11:21 A.M<br \/>\nwe get 11:21 A.M. &#8211; 24 minutes = 10:57 A.M<br \/>\nso the answer is 10:57 A.M.<\/p>\n<h3>Measure Elapsed Time Across the Hour Homework &amp; Practice 12.3<\/h3>\n<p>Find the elapsed time.<\/p>\n<p>Question 1.<br \/>\nStart: 3:50 P.M.
