Correct option is B
Given:
A person takes 1 hour more when walking at 2 km/h compared to 3 km/h
We are to find the distance
Formula Used:
Time = Distance / Speed
Difference in time = 1 hour
Solution:
Let the distance be D km
Time taken at 2 km/h = D ÷ 2
Time taken at 3 km/h = D ÷ 3
According to the question:
D / 2 − D / 3 = 1
Take LCM of 2 and 3 = 6
(3D − 2D) / 6 = 1
=> D / 6 = 1
=> D = 6 km
Final Answer:
S. Ans. (B) 6 km
