SOLUTION: The time "t" required to empty a tank varies inversely as the rate "r" of the pumping. If a pump can empty a tank in 45 minutes at a rate of 600 kL/min, how long will it take a pum

Question 92093: The time "t" required to empty a tank varies inversely as the rate "r" of the pumping. If a pump can empty a tank in 45 minutes at a rate of 600 kL/min, how long will it take a pump to empty the same tank if its rate is 1000 kL/min?

t varies inversely with r, so
We need to find k. Let t=45 and r=600

So our formula therefore is:
If r=1000 kL/min then:
min
t=27 min
Happy Calculating!!!
