Question

The time it takes to will a water tank varies inversely with the water rate of the hose. At 8 gallons per minutes, a hose can fill the tank in 45 minutes. How long will it take to fill the same tank at 15 gallons per minute?​

Answer 1

24 minutes

Explanation:

Varies inversely

tr = k

At 8 gallons per minutes, a hose can fill the tank in 45 minutes

k = 45 * 8 = 360

How long will it take to fill the same tank at 15 gallons per minute?​

t * 15 = 360

Divide both sides by 15

t = 24
