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 by dividing the total distance of 400 miles by the time of 8 hours:
Average speed on first route = 400 miles / 8 hours = 50 mph
The average speed on the second route can be calculated by dividing the total distance of 420 miles by the time of 7 hours:
Average speed on second route = 420 miles / 7 hours = 60 mph
The difference in average speed between the two routes is:
60 mph - 50 mph = 10 mph
Therefore, your average speed will be 10 mph higher on the faster route.
