Question

A water tank already contained 24 gallons of water before a pump was switched to fill it. The pump started at 10:00 am and by 10:30 am the tank contained 40 gallons of water. By 1:00 pm the tank contained 120 gallons of water. b Write an equation which will tell the amount of water that the tank containes (W) after the pump was working for T hours.

Answer 1

So the equation which will tell the amount of water is

W= 24 + 32 T

Explanation:

Given,

A water tank already contain 24 gallons of water before the pump was switched to fill it. The pump started 10:00 am and by 10:30 am the tank contained 40 gallons of water . By 1:00 pm the tank contained 120 gallons of water.

The pump filled the tank (40 -24) = 16 gallons in 30 mins.

The pump filled (16 × 2 ) gallons =32 gallons in 1 hour.

So the equation which will tell the amount of water is

W= 24 + 32 T
