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.
