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?
can someone please help, my parents can’t help either ☹️
x = time it takes for the second pipe to fill the tank x-2 = time it takes for both pipes to fill the tank 1/4 = portion of the tank filled by the first pipe in one hour 1/x = portion of the tank filled by the second pipe in one hour 1/(x-2) = portion of the tank filled by both pipes
