Question

It takes Benjamin 28 minutes to mow 2 lawns. How long does it take him to mow 1 lawn? Assuming the lawns are the same size and Benjamin works at the same speed, how long will it take him to mow 5 lawns?

Answer 1

70

Explanation:

divide 28 by two to figure out how long it takes him to mow one lawn, the multiply it by 5 to figure out how long it would take him to mow five.

Answer 2

14 minutes per lawn

70 minutes

Explanation:

Divide 28 by 2 to find a unit rate.

28 min per 2 lawns = (28 min)/(2 lawns) = (14 min)/(lawn)

Multiply the unit rate by 5 to find the amount of time for 5 lawns.

5 * (14 min/lawn) = 70 min
