The following table compares the speed you drive in km/h to the fuel economy in km/L. Find the speed you need to travel to max your fuel economy.

Speed 24 32 40 48 56 64 72 80 89 97 105 113
Fuel Economy 9.48 10.84 11.69 12.33 12.24 12.75 12.71 12.84 12.92 12.24 11.65 10.76

To find the speed at which the fuel economy is maximized, you need to identify the highest value in the "Fuel Economy" column.

Here's a step-by-step explanation of how to determine the speed at which fuel economy is maximized:

1. Create a data table with the "Speed" and "Fuel Economy" values provided:

| Speed | Fuel Economy |
|-------|--------------|
| 24 | 9.48 |
| 32 | 10.84 |
| 40 | 11.69 |
| 48 | 12.33 |
| 56 | 12.24 |
| 64 | 12.75 |
| 72 | 12.71 |
| 80 | 12.84 |
| 89 | 12.92 |
| 97 | 12.24 |
| 105 | 11.65 |
| 113 | 10.76 |

2. Look for the highest value in the "Fuel Economy" column. In this case, 12.92 is the highest value.

3. Identify the corresponding value in the "Speed" column for the highest fuel economy value. In this case, the speed that maximizes fuel economy is 89 km/h.

Therefore, to maximize your fuel economy, you need to travel at a speed of 89 km/h.
