5. Two water taps together can fill a tank in 9 hours. The tap of the larger diameter
takes 10 hours less than the smaller one to fill the tank separately. Find the time in which
each tap can separately fill the tank.

a. How would you represent the time taken by the smaller tap to fill the tank
completely? How about the bigger tap?

b. How would you express the volume of the tank filled by the smaller tap in one
hour? How about the bigger tap?

c. What equation represents the time they fill the tank together?

d. How long does each tap fill the tank separately?​
