Question

the speed of train a is 6 mph slower than the speed of trainb. train a travels 200 miles in the same time it takes train b to travel 230 miles. find the speed of each train.

Answer 1

Let the speed of train a is x and that of train b is y
y-x=6
let the time taken to reach this distance is t
xt=200
yt=230
x/y=20/23
by solving the to equations simultaneously
x=40 mph
y=46 mph

Answer 2

Train a 200 miles 
train b 230 miles
