Question

Michael and his sister Mel share the job of mowing the grass in their yard. Michael mows ⅓ of the yard, and Mel mows the rest. Mel can mow ¾ of the entire yard in an hour.

How long will it take Mel to finish mowing the yard? Show your work.

Answer 1

0.89 hours

Explanation:

Micheal and his sister Mel share the task of mowing the grass in their yard.

Micheal mows 1/3 of the yard

= 1-1/3

= 2/3

Mel mows the rest portion

Mel can now mow 1/3 of the yard in one hour

Therefore the time taken by Mel to finish mowing the yard can be calculated as follows

= 2/3 ÷ 3/4

= 2/3 × 4/3

= 8/9

= 0.89 hours

Hence it will take Mel 0.89 hours to finish mowing the yard
