Will someone answer this for me please, I'd really appreciate it.

john is draining a pool he has two pumps but he can only use one at a time he know that the time a pump takes to drain the pool varies inversely with the power in watts of the pump his old pump is a 80 watt pump and it can drain the pool in 5 hours how long would the job take if he uses his new 100 watt pump

Tldr version: if it take 5 hours to pump a pool with an 80 watt pump how long will it take with a 100 watt pump

Please.

Answering this question with logic would show that it only needs some very basic maths.
BASIC ASS MATHS, DO YOUR OWN DAMN HOMEWORK

use cross multiplication so 5 times 100 is 500 divided by 80 is 6.25 so 6 hours and 15 min
