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)

The average speed on the first route can be calculated as 400 miles divided by 8 hours, which equals 50 mph.

The average speed on the second route can be calculated as 420 miles divided by 7 hours, which equals 60 mph.
Therefore, the average speed on the faster route is 60 mph, while the average speed on the slower route is 50 mph. The difference between the two average speeds is 60 mph - 50 mph = 10 mph.
