Question

Joe is filling the washing machine to wash clothes. After one minute, there are 1.75 gallons of water in the washing machine. After two minutes, there are 3.5 gallons of water in the machine. After three minutes, there are 5.25 gallons in the machine. If this pattern continues, how many gallons of water will be in the washing machine after six minutes?

Answer 1

Final answer is 10.5 gallons of water.

Explanation:

Given that Joe is filling the washing machine to wash clothes. After one minute, there are 1.75 gallons of water in the washing machine. After two minutes, there are 3.5 gallons of water in the machine. After three minutes, there are 5.25 gallons in the machine. Now we need to determine If this pattern continues then about how many gallons of water will be in the washing machine after six minutes.

Look at the pattern of volume of the water at given minutes.

We see that 1.75 is added each minute.

then required equation of volume is

V=1.75t

So for t=6 minutes, volume is given by

V=1.75*6=10.5

Hence final answer is 10.5 gallons of water.
