Question 1094259: An airplane travels 2040 miles in the same time that a car travels 210 miles. If the rate of the plane is 366 miles per hour faster than the rate of the car, find the rate of the plane. Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! Let n be the speed of the car. Then the plane would be n+366. So:
2040/n+366=210/n
2040n=210n+76860
1830n=76860
n=42
The car goes 42 mph; the plane goes 408 mph.
