Answer:
7.5 minutes
Step-by-step explanation:
If we let x represent the number of minutes it takes for the cold faucet to fill the tub, then it takes 2x minutes for the hot faucet. The total rate of filling in tubs per minute is ...
1/x + 1/(2x) = 1/5
Multiplying by 10x, we have ...
10 + 5 = 2x
x = 15/2 = 7.5
It takes the cold faucet 7.5 minutes to fill the tub.
