<PRE><B>Question 952377</B>
A plane can fly 900 miles in the same time as it takes a car to go 250 miles. If the car travels 130 mph slower than the plane, find the speed of the plane.
***
let x=speed of the plane
x-130=speed of the car
travel time=distance/speed
..
{{{900/x=250/(x-130)}}}
900(x-130)=250x
900x-117000=250x
650x=117000
x=195
speed of the plane=195 mph</PRE>
