A man travelled first half of his journey at a speed of 60 kmph and the second half of his journey at a speed of 40 kmph. Find the average speed of the man
A48 kmph
B50kmph
C55 kmph
D45 kmph
Answer:
B. 50kmph
Read Explanation:
The average speed of the man = the average of both the speeds (here it is the average of both the speeds because the distance travelled with respective speeds is equal).
The average speed = 60 + 40 / 2 = 100 / 2 = 50 kmph
