1) Write your equation with the given variables
*You have to determine what type of variation you have!
2) Solve for your constant of variation (k)
3) Write your equation again with the
constant you solved for in step 2.
4) Make your prediction.
Three types of Variation
The time T required to empty a tank varies
inversely as the rate r of pumping. If a Briggs
pump can empty a tank in 45 minutes at a rate of 600 kL/min, how long will it take to the pump to
empty the tank at 1000 kL/min?
