If Sohail walks from his home to office at 16 km/h, he is late by 5 min. If he walks at 20 km/h, he reaches 10 min before the office time. Find the distance of his office from his house.

A) 22 km
B) 20 km
C) 18 km
D) 16 km

Correct Answer:


B) 20 km

Description for Correct answer:
Let required distance = x

According to the question,

\( \Large \frac{x}{16} - \frac{x}{20} = \frac{15}{60} => \frac{5x-4x}{80}=\frac{1}{4} \)

\( \Large x = \frac{1}{4} \times 80 = 20 km \)
