Question

It takes Amelia 45 minutes to rake her yard every Saturday during the fall. It takes Andy 1 hour to rake the same yard. If Amelia and Andy work together, how long will it take them to rake the yard? Round your answer to the nearest minute.

Answer 1

Answer: 26 mins

Explanation:
2 Amelias would take 45/2 (22.5) minutes,
2 Andys would take 60/2 (30) minutes.
We first need to find the average of 60 and 45, which is 52.5,
Then we need divide 52.5 by 2.
The answer is 26.25, and round it to the nearest minute equals 26 mins.
