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.
