Jason and his twin brother, Seth, are painting the walls in their bedroom. It took Jason 50 minutes to paint a 160-square-foot wall. It took Seth 30 minutes to paint a 120-square-foot wall. Who painted faster?

• Jason

• Seth

Answer explanation

To find who painted faster, compare their unit rates. See which one painted more square feet per minute.

Jason painted a 160-square-foot wall in 50 minutes.

Find the unit rate.

160square feet÷50 min =3.2square feet per min

Seth painted a 120-square-foot wall in 30 minutes.

Find the unit rate.

120square feet÷30min = 4square feet per min

4 square feet per minute is faster than 3.2 square feet per minute. So, Seth painted faster.
