Question

A bicyclist rides 12 miles in 132 minutes. if she continues at this speed, how long will it take her to travel 66 miles?

Answer 1

12/132 = 66/x...12 miles to 132 min = 66 miles to x min

cross multiply because this is a proportion

(12)(x) = (132)(66)

12x = 8712

x = 8712/12

x = 726 minutes or 12 hrs and 6 minutes

so the answer is 726

hope this helped
