Michael and his sister Mel share the job of mowing the grass in their yard. Michael mows 1/3
of the yard, and Mel mows the rest. Mel can mow 3/4 of the entire yard in an hour. How long will it take Mel to finish mowing her part of the yard?

Approximately 53 mins

Step-by-step explanation:

Yard mowed by Michael = ⅓ of the yard

Yard mowed by Mel = 1 - ⅓ =

Rate at which Mel can mow a yard = ¾ of the yard in 1 hour

That is, it would take 1 hr to mow ¾ of the yard.

If ¾ yard requires 1 hr, then,

⅔ yard would require x hr

Thus:

x*¾ = 1*⅔

Cross multiply

Divide both sides by 9

It would take Mel to finish mowing her part, which is approximately 53 mins. .
