Two cars leave town at the same time in opposite directions. the average rate of speed of one car is 15 miles per hour faster than the average rate of speed of the other car. the cars are 375 miles apart after 3 hours find the average weight of speed of the two cars.

The average rates of speed are 55 and 70 mph (miles per hour)

Step-by-step explanation:

3x+3*(x+15)=375

6x+45=375

6x=330

x=55
