Question

A mason can lay 20 bricks in 30 minutes. At this rate, how long will it take him to lay 100 bricks?​

Answer 1

Ok so you can do 100 divided by 20 which is equal to 5 so now you can multiply that by 30 which is 150 so if you need it in hours and minutes you’d divide 150 by 60 because there are 60 minutes in an hour and you get 2hours and 30minutes or you can leave it at 150minutes
