Question

The speed of a passenger train is 14mph faster than the speed of a freight train. The passanger train travels 290 miles in the same time it takes the freight train to travle 220 miles.
Find the speed of both trains........

would I use r=d/t?

Answer 1

Sort of. v=d/t
t=d/v
d1/v=d2/v2
(220)/v=(290)/(v+14)
v in this case is the speed of the freight train.
solve for v

Answer 2

k thanks :)
