find both speeds? Answer by lwsshak3(11628) (Show Source):
You can put this solution on YOUR website! A train travels 150 miles
in the same time that a plane
covers 400 miles.
if the speed of the plane is 20mph
less than three times the
speed of the train;
find both speeds?
***
let x=speed of train
3x-20=speed of plane
travel time=distance/speed (same for both plane and train)
400x=450x-3000
50x=3000
x=60
3x-20=180-20=160
speed of train=60 mph
speed of plane=160 mph
