Problema Solution
Two trains start from towns 240 mi apart and travel towards each other on parralel tracks. They pass each other 1.6 hr later. If one train travels 10 mph faster than the other, find the speed of each train.
Answer provided by our tutors
Let
speed of 1st train = x
speed of 2nd train = x+10
Since speed*time = distance we can write:
1.6x + 1.6(x + 10) = 240
........
click here to see the equation solved for x
........
x = 70 mph
70+10 = 80 mph
The speeds of the trains are 70 mph and 60 mph.
