To determine how long a 1.45-gallon fuel tank will last, one must consider the fuel consumption rate of the engine or device using the tank. If the rate of fuel consumption is given or can be calculated, it can help in finding out the duration the tank will last.

In this situation, let’s assume you are provided with specific fuel consumption, which indicates how much fuel (in gallons) the engine uses per hour. For instance, if the engine consumes 0.53 gallons per hour, one can calculate the duration by dividing the total fuel capacity of the tank by the rate of consumption:

1.45 gallons / 0.53 gallons per hour ≈ 2.75 hours.

This calculation correctly reflects how long the tank would last under steady operation at that consumption rate. Therefore, the accurate answer, in this context, is the duration that corresponds to the fuel consumption and is reflected in the choice labeled as C.

Thus, the 1.45-gallon fuel tank can be expected to last approximately 2.75 hours based on the fuel consumption scenario provided.
