Wilma can mow a lawn in 90 minutes. Vanessa can mow the same lawn in 30 minutes.
How long does it take for both Wilma and Vanessa to mow the lawn if they are
working together?

Respuesta :

GoingSleepy

Answer:

If it takes Wilma 90 minutes and Vaness 30 minutes you'll need to add 90 + 3.

If add both numbers correctly the answer that you'll get will be 2 hours.

Hope this helped :)
