Find the distance traveled by the pedestrian if his speed is 6 km / h and the walking time is 2 hours 30 minutes.

There is a path formula that says distance = travel speed * travel time.

Using this formula, we can easily calculate how far a pedestrian traveled while moving at a speed of 6 km per hour, if the time he spent on the way was 2 hours 30 minutes.

2 hours 30 minutes = 2.5 hours.

S = 6 * 2.5 = 15 km.

Therefore, we can conclude that the pedestrian covered a distance of 15 km.
