Question
A man covers a certain distance by car driving at 10 KMPH and he returns the same distance at 15 KMPH Find his Average speed
Solution
To calculate the average speed, we need to use the formula for average speed when the distance covered at different speeds is the same. The formula is:
Average speed = 2xy / (x+y)
where x and y are the two speeds. In this case, x = 10 KMPH and y = 15 KMPH.
So, the average speed = 21015 / (10+15) = 300 / 25 = 12 KMPH.
Therefore, the man's average speed for the entire journey is 12 KMPH.
