The hose fills the tank at a rate of 4548 litres/ hour.
Explanation:
GIVEN:
The rate at which the hose fills the tank = 20 gallons per minute.
One gallon is 3.79 litres.
To Find:
The rate in litres per hour=?
Solution:
The total number of litres = rate at which the hose fills tanks * quantity of one gallon
The total number of litres = 20 x 3.79.
The total number of litres = 20 x 3.79.
The total number of litres = 75.8
Per minute is 1/60 hours.
= 75.8/ 1/60
= 75.8*60 litres/hr.
= 4548 litres/ hour.
