The time (t) required to empty a tank varies inversely as the rate (r) of pumping. A pump can empty a tank in 90 minutes at the rate of 1200 L/min. How long will the pump take to empty the tank at 3000 L/min?

36 minutes.
90 x 1200 = 108000. There are 108,000 Liters in the tank.
108,000/3000= 36 minutes.

enable x be the gap from the element on the floor to the backside of the construction. enable h be the top of the flagpole. Then: tan 32° = (27 m) / x tan 40 3° = (27 m + h) / x From the 1st equation, x might nicely be deduced to be x = (27 m) / (tan 32°) = 40 3.2 m Plug in x into the 2nd equation and remedy for h.
