How much will it cost you to drive 217 miles?

To calculate the cost of driving 217 miles, we need to know the fuel efficiency of the car and the current fuel price. Without this information, I can't provide a precise cost.

However, I can give you a general formula to calculate the cost of driving any distance:

```

Cost = (Distance / Fuel Efficiency) * Fuel Price

```

Here, Distance is the number of miles you intend to drive (in this case, 217 miles), Fuel Efficiency is the average miles per gallon (mpg) of your car, and Fuel Price is the current price of fuel per gallon.

For example, if your car has a fuel efficiency of 30 mpg and the fuel price is $3 per gallon, the cost to drive 217 miles would be:

```

Cost = (217 / 30) * 3 = $21.70

```

This calculation gives you a rough estimate of the fuel cost for your trip. It's worth noting that other factors like traffic conditions, vehicle speed, and additional fuel costs (like tolls) can affect the actual cost of driving.
