Question

Can you guys help me, I need the answer asap!

1. Robert can paint a house in 3 hours and 15 minutes. Maggie can finish the same job in 5 hours and 12 minutes. How long will it take them to finish the job?

Answer 1

Answer:

2 Hours

Let together they finish in x mins.

Fist convert the time needed by both Robert and Maggie in mins.

Robert => 3 hrs 15 mins => 195 mins

Maggie => 5 hrs 12 mins => 312 mins

Now when they will work together,

1/195 +1/312 = 1/x

on solving we get x = 120

so Together they finish in 2 hrs or 120 mins.
