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
