Correct option is C
=
Given:
Walking speed of man = 3 km/h
Time taken at walking speed = 8 hours
Running speed of man = 16 km/h
Formula Used:
Distance (D) = Speed × Time
Solution:
Calculate the distance covered when walking:
D =
Now, use the running speed to find the time required to cover the same distance:
Time} =
Time =
The man will take 1.5 hours to cover the same distance at a speed of 16 km/h.
