If one person can finish mowing a field in 4 hours and another person can finish mowing a field in 8 hours. How long do you think it'll take to finish mowing the field if they work together?

Answer 1

Every hour A finishes 1/4 of the work, and B finishes 1/8 of the work.
Together they finish 3/8 of the work in one hour.
How long would it take A and B to finish 8/8 of the work?

Answer 2

yeah I did mine wrong. Hopefully I'll get partial credit on the test.

Answer 3

I would give partial credit to an answer with the right approach but with a minor mistake in the numbers. Good luck.
