Question 356427: Next door neighbors Angelina and Brad use hoses from both houses to fill Brad's swimming pool. They know that it takes 18 hours using both hoses. they also know that Brad's hose, used alone takes 20% less time than Angelina's hose alone. Calculate how much time is required to fill the pool by each hose alone. Answer by ewatrrr(24785) (Show Source):
Hi,
Let t be the time of Angina's hose, then .80t is the time for Brad's hose
multiply each term on both sides of the equation by .8*18*t
t = 40.5 hr
Angina's hose takes 40.5 hr alone
Brad's hose takes .8*40.5 = 32.4 hr alone
