Richard had empty tank on arrival in town. If his car holds 40 L,what must have been the fuel consumption rate of his car?

To calculate the fuel consumption rate of Richard's car, we need to know how much fuel he used to travel to the town. Since he arrived with an empty tank, we can assume that he used all 40 liters of fuel in his tank to travel to the town.

Therefore, the fuel consumption rate of his car can be calculated as:

Fuel consumption rate = Total fuel used / Distance traveled

Since we do not have information about the distance traveled, we cannot calculate the exact fuel consumption rate. However, if we assume that Richard used all 40 liters of fuel to travel a certain distance, we can calculate the fuel consumption rate based on that distance.

The provided text don't have enough information about the fuel consumption rate, so I can't answer this question from the provided context.
