A train traveling at 60 m.p.h,Arrives at a station 100 miles away 15 min later than schedule
At what speed should it travel to arrive exactly on time?
Find the actual time of the train
100%2F60 = 12%2F3
change 15 min to 1%2F4
12%2F3 - 1%2F4 = 1.4167 hr is the desired time
Let s = the desired speed
100%2Fs = 1.4167
s = 100%2F1.4167
s = 70.6 mph
