Question

A standard showerhead dispenses 50 gallons of water in 20 minutes. At this rate, how many gallons of water will a standard showerhead dispense in 5 minutes?

F. 12.5 gallons
G. 2.5 gallons
H. 37.5 gallons
J. 2 gallons

Answer 1

12.5 gallons

Explanation:

Make a proportion

50 gallons of water in 20 minutes, and x gallons of water in 5 minues

50/20=x/5

To solve, we need to get the variable, x, by itself. Right now, it is being divided by 5. To get rid of this, multiply both sides of the equation by 5

5(50/20)=(x/5)5

This will allow the 5s on the right to cancel, leaving us with

12.5=x

Answer 2

= 12.5 gallons

Explanation:

50 gallons per 20 mins

50/20=5/2

5/2 per minute so 5 mins is

5/2 x 5 = 25/2

=12.5 gallons
