It takes arman 48 minutes to mow 4 lawns. Assuming the lawns are the same size and Arman works at the same speed, about how long will it take him to mow 7 lawns?
Arman need 48 minutes to mow 4 lawns with the lawns are the same size. so every 1 lawns he need time 48/4=12 minute. If he to mow 7 lawns he will take 12x7=84 minutes.
