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

First do 28/2 to find min per lawn

It's 14

Then do 14 x 5 to find out how many minutes it take him to mow 5 lawns

It's 70

FYI 70 min is 1 hr n 10 min

well divide 28 by 2 and you'll get the time that he takes per lawn;

28/2 = 14

so for now 5 lawns you just need to multiply 14 mins per 5 lawns and you get your final answer as;

70 minutes in total of the 5 lawns
