Question

It takes Mark 3 minutes to make 1 1/2 inches of a bracelet. If he works at the same speed, how many minutes will it take him to make a 12-inch bracelet

Answer 1

24 minutes

Explanation:

Working at the same speed, the ratio of time to length is the same:

time/length = t/12 = 3/(1.5)

t = 12(3/1.5) = 12(2) = 24

It will take Mark 24 minutes to make a 12-inch bracelet.
