A car travelling at 25 km per hour and gets 5 km per litre of gasoline, how long can the car travel on 20 litres of gasoline?

At that speed, it can go

20 liters x 5 km/liter = 100 km

It will a shorter distace at higher speed.

To find out how long the car can travel on 20 liters of gasoline, we need to determine the total distance the car can cover with that amount of fuel.

First, let's calculate the distance the car can travel on 1 liter of gasoline. We know that the car gets 5 km per litre, so it can travel 5 km on 1 liter of gasoline.

Next, we need to find out the total distance the car can travel on 20 liters of gasoline. To do this, we multiply the distance the car can cover on 1 liter of gasoline (5 km) by the number of liters (20).

Mathematically, this can be represented as:
Total distance = Distance per liter * Number of liters
Total distance = 5 km/l * 20 liters
Total distance = 100 km

Therefore, the car can travel a total distance of 100 km on 20 liters of gasoline.
