Question

PLS I NEED HELP!!! If Mary can paint 1/4 of a wall in 20 minutes, how long will it take her to paint a room with 4 walls?

Answer 1

Answer: 320 minutes

Explanation:

1/4 of a wall takes 20 minutes, therefore one wall takes 80 minutes. Multiply that by 4 for 4 walls, and that becomes 320 minutes.

Answer 2

80 minutes

Explanation:

One wall takes 20 minutes, so 20×4=80 minutes.
