Ahose fills a tank at a rate of 20 gallons per minute what is the rate in liters per hour

The hose fills the tank at a rate of 4548 litres/ hour.

Step-by-step 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.

step-by-step explanation:

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
