Answer:
55
Step-by-step explanation:
You can do:
81 - 26 = 55
The sum of the angles (81) minus the angle that is represented (21)
Pump A fills 1/4 of the tank per hour, and pump B fills 1/6 of the tank per hour. Working together, then, they fill 5/12 of the tank in an hour.
As a result, after one hour, they fill 5/12 of the tank. After the next hour, 2/3 is filled, because only 1/4 of the tank is filled since Pump B is broken.
In the third hour, 1/3 of the tank is left. This takes (1/3)/(5/12), or 4/5, of an hour. This is 48 minutes.
Therefore, it takes two hours and 48 minutes to fill the tank, finishing at 10:48.
