Using my faucet, it takes 6 minutes to fill our water tank. Using my neighbor's hose, it takes 9 minutes. How long would it take if i used both the faucet and the hose?

1/6 + 1/9 = x

3/18 + 2/18 = x

x = 5/18 * 1

x = 18/5

x = 3.6 minutes

use this formula

t/a+t/a=1

where t=together and a=alone

x/6 + x/9 = 1

(6x+9x)/54 =1

15x=54

x=54/15

x=3 3/5 minutes = 3minutes 36 seconds
