Question

If Frances can paint 1/3 of a wall in 20 minutes, how long will it take her to paint a room with 4 walls.

A. 60 minutes
B. 80 minutes
C. 240 minutes
D. 266 minutes

Answer 1

C. 240 minutes

Explanation:

If 1/3 of a wall takes 20 minutes, then 3/3 of a wall would take 60 minutes(hour). Then multiply 60x4 and you get 240.

20x3=60

60x4=240
