Which truck drove the fewest number of miles per gallon of gas?
truck A
truck B
truck C
truck D

Answer 1

To determine which truck drove the fewest number of miles per gallon of gas, we can calculate the miles per gallon for each truck using the formula:

\[
\text{Miles per gallon} = \frac{\text{Miles Driven}}{\text{Gallons Used}}
\]

Let's calculate this for each truck:

- **Truck A:**
\[
\text{Miles per gallon} = \frac{45 \text{ miles}}{3 \text{ gallons}} = 15 \text{ miles per gallon}
\]

- **Truck B:**
\[
\text{Miles per gallon} = \frac{24 \text{ miles}}{2 \text{ gallons}} = 12 \text{ miles per gallon}
\]

- **Truck C:**
\[
\text{Miles per gallon} = \frac{14 \text{ miles}}{1 \text{ gallon}} = 14 \text{ miles per gallon}
\]

- **Truck D:**
\[
\text{Miles per gallon} = \frac{36 \text{ miles}}{4 \text{ gallons}} = 9 \text{ miles per gallon}
\]

Now we can compare the miles per gallon for all trucks:

- Truck A: 15 miles per gallon
- Truck B: 12 miles per gallon
- Truck C: 14 miles per gallon
- Truck D: 9 miles per gallon

The truck that drove the fewest number of miles per gallon is **Truck D**, with 9 miles per gallon.
