Question

Amy can wash 25 windows in 4 hours rodger can wash 32 in 6 hours how many can they wash in 12 hours

Answer 1

Find the unit rate for Amy and Rodger.


Amy: 25/4= 6.25 

Rodger: 32/6= 5.3333 repeating.

Multiply each by 12. 

6.25*12= 75

5.33333*12= 63.9999996 (round up to 64)

64+75= 139

They can wash 139 windows in 12 hours.

I hope this helps!
