: Two pipes are used to fill a water storage tank. The first pipe can fill the tank in 4 hours, and the two pipes together can fill the tank in 2 hours less time than the second pipe alone. How long would it take for the second pipe to fill the tank? This question is from textbook college algebra
You can put this solution on YOUR website! Call the time it takes to fill the 2nd tank x hrs
Rate of filling 1st tank + rate of filling 2nd tank = combined rate of filling
1 tank / 4 hrs + 1 tank / x hrs = 1 / (x-2) hrs
x = 4 hrs answer
