You can put this solution on YOUR website! Two trains are start from the same point and travel in. Train A travels East at an average speed of 75 mph and train B travels West at an average speed of 60 mph. How long will it take for the trains to be 297 miles apart?
;
Let t = time in hrs to be 297 mi apart
;
Write a distance equation; dist = speed * time
;
Train A dist + Train B dist = 297 mi
75t + 60t = 297
:
135t = 297
t =
t = 2.2 hrs to be 297 mi apart
:
:
Check solution:
75*2.2 + 60*2.2 =
165 + 132 = 297
