A man walked from his home to the market,at a distance of 12km.he spent 4 hours,find his average speed
Average speed is calculated by dividing the total distance traveled by the total time taken.
In this case, the man traveled 12 km in 4 hours.

Average speed = 12 km / 4 hours
Average speed = 3 km/h
Therefore, his average speed was 3 km/h.
