Answer:
17.5 km/liter
Step by step solved:
To calculate the fuel efficiency of the vehicle, we need to use the formula:
Fuel efficiency = Distance traveled / Amount of fuel used
In this case, the distance traveled is 350 km and the amount of fuel used is 20 liters. Therefore, the fuel efficiency of the vehicle is:
Fuel efficiency = 350 km / 20 liters = 17.5 km/liter
The units of fuel efficiency are kilometers per liter (km/liter).
