Problem:
Two faucets can fill a tank in 1 hour and 20 minutes. The first faucet takes more than 2 hours to fill the same tank when functioning without the second tap. How long does it take to fill each one separately?
Representation:
time for first faucet = (t + 2) hours
time for second faucet = t hours
1 hour and 20 minutes = 1 20/60 or 1 1/3 or 4/3 hours
Illustration:
Solution:
use t = 2 because it is a positive value
Checking:
time for first faucet = (t + 2) hours = 2 + 2 = 4 hours
time for second faucet = t hours = 2 hours
