2. Two pipes are used to fill a water tank. The first pipe can fill a tank in 4 hours
alone. The two pipes can fill a tank in 2 hours less time than the second pipe
alone. How long will it take the second pipe to fill the tank alone?
a. How will you represent the length of the time the second pipe can fill the
tank alone? How will you represent the length of the time the two pipes can
fill the tank together?
b. How will you represent the part of the tank filled by the first pipe alone in
one hour? How will you represent the part of the tank filled by the second
pipe alone in one hour? How will you represent the part of the tank filled
by the two pipes together in one hour?c. Formulate an equation relating the part of the tank filled by the first pipe alone, part of the tank is filled by the second pipe alone and the part of the tank filled by two pipes together. d. Using the equation, how long will it take the second pipe to fill the tank alone? e. how will you justify your answer?​
