Question 755969: Two trains are 351 miles apart, and their speeds differ by 21 mph. Find the speed of each train if they are traveling toward each other and will meet in 3 hours Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! You can think of one train as standing still and the
other one approaching at the sum of their speeds.
--------------
Let the speed of the slower train = mi/hr
The speed of the faster train = mi/hr
--------------
The speeds are 69 mi/hr and 48 mi/hr
check:
The faster train:
The slower train:
--------------- mi
and mi
OK
