Question 912986: A train travels 100 km in the same time that a plane covers 250 km. If the speed of the plane is 30 km per hour less than 3 times the speed of the train, find both speeds. The train's speed and the planes speed. Answer by lwsshak3(11628) (Show Source):
You can put this solution on YOUR website! A train travels 100 km in the same time that a plane covers 250 km. If the speed of the plane is 30 km per hour less than 3 times the speed of the train, find both speeds. The train's speed and the planes speed.
***
let x=speed of train
3x-30=speed of plane
travel time=distance/speed
250x=100(3x-30)
250x=300x-3000
50x=3000
x=60
3x-30=180-30=150
speed of train=60 km/hr
speed of plane=150 km/hr
