Question 895071: Suppose that during a test drive of two cars, one car travels 252 miles in the same time that the second car travels 210 miles. If the speed of one car is 14 miles per hour faster than the speed of the second car, find the speed of both cars.
You can put this solution on YOUR website! Suppose that during a test drive of two cars, one car travels 252 miles in the same time that the second car travels 210 miles. If the speed of one car is 14 miles per hour faster than the speed of the second car, find the speed of both cars.
***
let x=speed of slower car
x+14 speed of faster car
travel time=distance/speed
210/x=252/(x+14)
252x=210(x+14)
252x=210x+2940
42x=2940
x=70
x+14=84
speed of slower car=70 mph
speed of faster car=84 mph
