Question

One car travels 390 miles in the same amount of time it takes a second car traveling 3 miles per hour slower than

the first to go 372 miles. What are the speeds of the cars?
The speed of the cars are
miles per hour.

Answer 1

The first car is traveling at 65 miles per hour and the second car is traveling at 62 miles per hour.
Step-by-step explanation:
390:x=372:(x-3)
372x=390(x-3)
372x=390x-1170
1170=390x-372x
1170/18=18x/18
x=65

x-3= 65-3=62
