Problema Solution
TWO TRAINS LEAVE FROM THE SAME POINT AT THE SAME TIME, TRAVELING IN OPPOSITE DIRECTIONS. ONE TRAVELS 13 MPH FASTER THAN THE OTHER. AFTER 4HR. THEY ARE 484 MILES APART. FIND THE RATE OF EACH TRAIN.
Answer provided by our tutors
Let speed of train#1 be x mi/hr
So speed of train#2 would be (x+13) mi/hr
After 4 hours, they would have travelled 4x and 4(x+13) mi respectively
Given that after 4 hours, they are 484 mi apart, so
4x + 4(x+13)= 484
8x + 13 = 484
8x= 484-13 = 432
Hence x = 54 mi/hr
Ans : Rate (speed) of each train is 54 mi/hr and 54+13 = 67 mi/hr
