To determine how far a truck driver can go on 35 gallons of gas, we first need to establish the distance he can travel with 28 gallons. If you're looking for a direct conversion based on that amount, we can find the miles per gallon (MPG) first, and then apply it to the 35 gallons.
Assuming you meant he can travel a certain distance \( D \) with 28 gallons of gas, you can calculate the distance he can cover with 35 gallons using the formula:
\[ \text{Distance with 35 gallons} = \left( \frac{D}{28} \right) \times 35 \]
If you can provide the distance he can travel on the 28 gallons, I can help you with the calculation.
