Question 1052334: Suppose that during a test drive of two cars, one car travels 185 miles in the same time that the second car travels 150 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.
The speed of the first car is
nothing mph, and the speed of the second car is
nothing mph.

Let r be the rate of the slower car. Given that the times are equal, we have:
150/r=185/r+14
150(r+14)=185r
35r=2100
r=60
The slower car travels 60 mph; the faster one goes 74 mph. ☺☺☺☺

D = rt
0r
t = D/r
Times the same for both
| Cross Multiplying to solve
185r = 150(r+14)
35r = 150*14
r =60mph
(r+14) = 74mph
