Question

Time/Distance/Speed

Distance between Train 1 and Train 2 = 95 miles.
Average speed of Train 1 = 45 mph.
Average speed of Train 2 = 60 mph.


If both trains leave at the same time and travel toward each other but on parallel tracks, in how much time will their engines be opposite each other? (Hint: When the engines are opposite each other, together the trains will have traveled 95 miles. Their relative speed of travel is the sum of their respective speeds, or 105 mph.)

Answer 1

time = distance / speed
= 95/ 105 = 0.905 hours or about 54.3 minutes or 54 minutes 17 seconds
