To determine how long it would take to fill up the tank, we need two key pieces of information:

1. The rate at which the gas pump is filling the tank, which is given as $\frac{2}{3}$ gallons per minute.
2. The total capacity of the gas tank (in gallons), which is not provided in the problem.

If you provide the capacity of the gas tank, I can calculate the time it would take to fill it. The formula for time is:

$\text{Time} = \frac{\text{Tank Capacity}}{\text{Rate of Filling}}$

In this case, the rate of filling is $\frac{2}{3}$ gallons per minute.

Would you like to provide the tank capacity, or do you need any additional assistance with this?

1. What is the total capacity of your gas tank in gallons?
2. How does the gas pump's rate affect the time needed to fill tanks of different sizes?
3. If the rate were $\frac{3}{4}$ gallons per minute, how would the time change?
4. How would the time calculation change if the rate varied throughout the process?
5. Can you think of another way to measure the efficiency of the gas pump?

Tip: Always check units when calculating time and rates to ensure consistency.
