Getting back to the problem, if its a balloon with X diameter, if we assume it to stretch then how do we know when its full? From the problem, it seems to say the balloon is 45 Cm BEFORE filling. If so, thats the starting point and the end point would be undefined because we don't know how far it will stretch. Also it doesn't say whether the balloon is at STP, ground level, or maybe on the top of Mt Everest or on the moon with no air. So how do you decide when the balloon is "filled"?
If instead, it was a hollow sphere with an unyielding surface and it fills with a liquid at the rate of 23.7L/s it would be a more valid problem.

Never has it been established at what pressure the ball is to be filled or to what final mass. Air is compressable (fortunately for earth), and the pressure of the flow rate might not be constant if the ball is rigid and the backpressure builds up. The pump supplying the air might reach its head pressure before the desired pressure in the ball is obtained.

My answer:

Never

I also have another question:
There is a pile of bark (shaped like a cone) diameter is 2.2m height is 0.9m. How many loads will it take with a wheelbarrow?
Wheelbarrow whole length is 90cm, 40cm is a pyramid of the length. The rest of the 50 cm is a rectanglar prism height is 20, lenght is 50, and width is 40cm. How many full trips will it take?

Do your own homework. It's not tricky, it's just mindless calculating and busy work.

I also get about 14 minutes or seconds, depending on the units of the pump's rate.

Also, I don't care if this is homework or a test or whatever, I prefer these better than all the lame "riddles" that have been posted lately.
