A car takes 3 hours to travel 3km at a constant speed on an open road. Calculate the speed of the car

3/3 = 1

1 km/hour

That's a mighty slow car. Must be a traffic jam.

speed = km/h

Car speed =

3 km/3hours =
1 km/1hour =
1 km/h

To calculate the speed of the car, you need to use the formula:

Speed = Distance / Time

In this case, the distance is given as 3 kilometers and the time is given as 3 hours. Substituting these values into the formula:

Speed = 3 km / 3 hours

Dividing 3 kilometers by 3 hours gives you the speed:

Speed = 1 km/h (kilometer per hour)

Therefore, the speed of the car is 1 kilometer per hour.
