Question

Noshwa is completing the bike portion of a triathlon. Assuming she travels 40 miles in 2.5 hours. How long will it take her to travel 72 miles? Use the unit ratio to solve the following problem.

Answer 1

X/72 = 2.5/40 divide denominators by 8

X/9 = 2.5/5 = .5 multiply by 9

X = 9(.5) = 4.5 hours

72/40 = 9/5. 9/5 times 2.5 = 9(1/2)- 4.5 hours
