Calculate Average Speed of a Cyclist

What is the average speed of a cyclist who travels 10 km in 2 hours?

Answer:

The average speed is 5 km/h.

The average speed is a physical quantity that expresses the relationship between the distance traveled by an object and the time taken to do so. Average speed relates the change in position to the time taken to make that change, and it is calculated as the distance traveled by an object divided by the time taken.

In this case, the cyclist travels 10 km in 2 hours. By converting 10 km to meters (1 km = 1,000 m) and 2 hours to seconds (1 h = 3,600 s), we can calculate the average speed:

Average Speed = Distance/Time

Distance = 10 km = 10,000 m

Time = 2 hours = 7,200 s

Therefore, Average Speed = 10,000 m / 7,200 s = 5 km/h

So, the average speed of the cyclist is 5 km/h, which is equivalent to 1.389 m/s.
