A man walks 6 km at a speed of 112 kmph, runs 8 km at a speed of 2 kmph and goes by bus another 32 km. Speed of the bus is 8 kmph. Find the average speed of the man in kmph. A) 4314 B) 4213 C) 2413 D) 3414
Correct Answer: Option B
Explanation:
Man walked 6 km at 1.5 kmph, again he walked 8 km at speed of 2 kmph and 40 km at a speed of 8kmph
time taken indivisually:
=> 6/1.5 = 4 m
=> 8/2 = 4 m
=> 40/8 = 5 m
Average speed of man= total distance/ total time
=> 54/13 =
kmph
