eric kweeder can paint a wall in 14 minutes. His brother, Jessup can paint the same wall in 35 minutes. How long will it take them working together to paint the wall?

Respuesta :

First find the rate of each painter given the time it takes for them each to complete the job.

Eric rate: 1/14 of the job per minute

Brother: 1/35 of the job per minute

Together: 1/14+1/35 = 7/70 = 1/10 of the job per minute

This means that the job will be completed in 10 minutes.

answer: 10 minutes
