a car travel 100 km at speed of 60 km /h. Calculate the average speed of the journey.

To calculate the average speed of a journey, you need to divide the total distance traveled by the total time taken. In this case, the car traveled 100 km at a speed of 60 km/h.

To find the time taken, you can use the formula:

Time = Distance / Speed

So, the time taken for the journey would be:

Time = 100 km / 60 km/h

To simplify the calculation, you can divide 100 by 60:

Time = 1.6667 hours

Therefore, the average speed of the journey would be:

Average Speed = Total Distance / Total Time
= 100 km / 1.6667 hours
≈ 60 km/h

Hence, the average speed of the journey is approximately 60 km/h.
