Two trains leave towns 855 miles apart at the same time and travel toward each other. One train travels 13 miles per hour slower than the other. If they meet in 5 hours, what is the rate of each train?

Answer :

The velocity of the two trains are 79m/s and 66m/s

What is velocity?

Velocity is the rate of change of displacement with time. It is a vector quantity and it is measured in meter per second.

Using addition of vectors:

The total displacement = d2-d1

displacement = velocity × time

Represent the velocity of faster train by v

therefore the velocity of the slower train = v -13

855 = 5v +5(v-13)

855 = 5v+5v+65

855 = 10v +65

10v = 855-65

10v = 790

v = 790/10

v = 79 m/s

the rate of the second train = 79-13 = 66m/s

therefore the rate of the two trains are 79m/s and 66m/s
