An above ground swimming pool is leaking. After 1/2 hour the pool has leaked 7/8 of a gallon of water. How many gallons of water per hour is the swimming pool leaking?

Respuesta :

Find the "unit rate."  Divide (7/8 gallon) by (1/2 hour):


(7/8) gallon      7       2
--------------- = ----- * ----- = 14/8 gal/hr, or 7/4 gal/hr.
(1/2) hour         8       1
