can you show me the solution of shower for the quick method? that the gpm is 1.5 ?

To solve for the water usage of a shower using the given gallons per minute (gpm) of 1.5, we can follow these steps:

1. Break Down the Problem

Identify the total time spent in the shower and how that relates to the gallons used.

2. Relevant Concepts

Understanding that the water usage can be calculated using the formula: $\text{Total Gallons Used} = \text{Gallons per Minute} \times \text{Total Minutes}$

3. Analysis and Detail

Assuming you take a shower for a certain number of minutes, let's denote the shower duration as $t$ minutes:

$\text{Total Gallons Used} = 1.5 \, \text{gpm} \times t$

4. Verify and Summarize

To summarize, for each minute you shower, you will use 1.5 gallons of water.

Final Answer

The total gallons used can be expressed as: $\text{Total Gallons Used} = 1.5 \times t \, \text{gallons}$ where $t$ is the duration of the shower in minutes. For example, if $t = 10$ minutes, then: $\text{Total Gallons Used} = 1.5 \times 10 = 15 \, \text{gallons}$
