<PRE><B>Question 698229</B>
Two trains, E and F travel along parallel tracks.
 Each track is 220 miles long. They begin their trips at the same time.
 Train E travels at a rate of 55 miles per hour and train F travels at a rate of 22 miles per hour.
 How many miles will train F have left to travel after train E completes its trip?
:
Find how long it takes Train E to make the trip (220 mi)
220/55 = 4 hrs
:
Find how far train F travels in 4 hrs
4*22 = 88 mi
then
220 - 88 = 132 mi to go for train F, when E completes the journey of 220 mi</PRE>
