Question

How many gallons of water will be in the fish tank after 3 minutes? 0.5 mins = 0.8 gallons

Answer 1

There will be 4.8 gallons in 3 minutes.

3 times 0.5 = 6

6 times 0.8 = 4.8 gallons of water in 3 minutes

Answer 2

0.8 gallons for 0.5 minutes.

Multiply by 2 to get gallons per minute :

0.8 x 2 = 1.6 gallons per minute

Multiply gallons per minute by 3 minutes:

1.6 x 3 = 4.8 gallons in 3 minutes.
