Question

Monica paints 4/5 of a room in 30 minutes. If he continues at this speed,how many rooms will he paint in 4 hours?

Answer 1

The equation (4/5*2)4 will solve it because there are 60 minutes in 1 hour, and 2 times the thirty minutes gives us the hourly rate. The hourly rate (1.6 rooms) will then be multiplied to the 4 hours, to get 6.4 rooms painted in a matter of 4 hours. Answer= 6.4 rooms
