Nilu covers a distance by walking for 6 h. While returning, his speed decreases by 2 km/h and he takes 9 h to cover the same distance. What was her speed while returning?

A) 2 km/h
B) 5 km/h
C) 4 km/h
D) 7 km/h

Correct Answer:



C) 4 km/h

Description for Correct answer:

Let the speed in return journey = x

According to the question,

6 (x + 2) = 9x

6x + 12 = 9x = 9x - 6x = 12

3x = 12

Therefore, x = \( \Large \frac{12}{3} \) = 4 km/h
