Max mows a yard in 45 minutes and Jan takes twice as long mowing the same yard. If Max and Jan both work together, it will take approximately 30 minutes to for them both to mow the yard.
It take Max 1 minute to mow 1/45 of the yard.
It takes Jan 1 minute to mow 1/90 of the yard.
1/45+1/90 =3/90 = 1/30 of the yard can be mowed by both in just one minute. This is how to get the answer, 30 minutes.
The room is 20 / 3 yd by 15 / 3 = 5 yd, which is (20 / 3) x 5 = 33.33 square yards. So the cost of carpeting would be 33.33 x 37 = $1233.33
