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) Responses 10 mph 10 mph 20 mph 20 mph 60 mph 60 mph 50 mph
To calculate the average speed, we use the formula:
Average speed = total distance / total time
For the first route, where it takes 8 hours to drive 400 miles:
Average speed = 400 miles / 8 hours = 50 mph
For the second route, where it takes 7 hours to drive 420 miles:
Average speed = 420 miles / 7 hours = 60 mph
Therefore, the average speed on the faster route is 60 mph, which is 10 mph higher than the average speed on the other route.
