Problema Solution

The speed of train A is 14 mph slower than the speed of train B. Train A travels 230 miles in the same time it takes train B to travel 300 miles.

Speed of train A is mph.

Speed of train B is mph.

Answer provided by our tutors

let speed of train B = x mph

then speed of train A = x-14 mph

same time travels then

t =250/(x-14) for train A

t = 300/x  for train B

250/(x-14) = 300/x

solve this equation then

x = 84 mph

then

speed of train A = 84 - 14 = 70 mph

speed of train A = 84 mph
