Jasmine finished the bike trail in 2.5 hours at an average rate of 9310miles per hour. Lucy biked the same trail at a rate of 615 miles per hour. How much longer did it take Lucy to bike the trail?

Answer 1

Answer:

time = 2.5 hours

average speed = 9310 mph

distance covered = 9310 × 2.5 = 23275 miles

Lucy's average speed= 615 mph

time taken by Lucy = distance/speed = 23275/615= 37.84 hours
