Question

A person was working on his homework for two hours. He spent 1/3 of his time doing math, and 1/4 of the rest of his time reading. How many minutes did he read?

Answer 1

20 min

Explanation:

120×1/3 = 40 min

remaining time 80 min

reading = 80×1/4 = 20 min

Answer 2

20 minutes.

Explanation:

After working on his math he had 2 - 1/3*2 = 1 1/3 hours left.

He read for 1/4 * 1 1/3

= 1/4 * 4/3

= 1/3 hours

= 20 minutes.
