Answer :

Answer:

To find out how many miles Louise biked per hour, we can divide the total distance she biked by the total time taken.

Total distance biked by Louise = 50 4/5 miles = 50 + 4/5 = 50 + 4/5 = 254/5 miles

Total time taken = 4 hours

To find the distance she biked per hour:

Distance per hour = Total distance / Total time

Distance per hour = (254/5) miles / 4 hours

Distance per hour = 254/5 miles * 1/4

Distance per hour = 254/20

Distance per hour = 12.7 miles

Louise biked approximately 12.7 miles per hour.
