You are going to drive to another state for a vacation. One route will take 8 hours to drive 400 miles, and the other route will take 7 hours to drive 420 miles. You write two equations to try and figure out the average rate of speed you would travel on each route. How much higher will your average speed be on the faster route?(1 point)

10 mph
The correct answer is 10 mph.
To calculate the average speed, you divide the distance by the time taken, so the equations would be:
For the first route: Average speed = 400 miles / 8 hours = 50 mph
For the second route: Average speed = 420 miles / 7 hours = 60 mph
Therefore, the average speed on the second route is 10 mph higher than on the first route.
