A person covers 28 km while walking at a speed of 8 km/h. How much distance (in km) will he cover in same time if he walks at a speed of 6 km/h?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 21.
Speed = distance/time
Given that
A person covers 28 km while walking at a speed of 8 km/h
if he walks at a speed of 6 km/h,
According to the question
For constant time, Speed is proportional to the Distance
Hence, the required distance = 28 × 6/8 = 21 km
