A) 50 km
B) 40 km
C) 55 km
D) 60 km
Correct Answer: B
Solution :
Let the total distance covered by him be x km. Distance covered by train \[=\frac{x}{2}\]km and the distance covered on foot \[=\frac{x}{2}\]km Time taken to cover \[\frac{x}{2}\]by train\[=\frac{x}{2\times 25}=\frac{x}{50}\]h Time taken to cover \[\frac{x}{2}\]on foot \[=\frac{x}{2\times 4}=\frac{x}{8}\]h According to the question,\[\frac{x}{50}+\frac{x}{8}=5\frac{48}{60}\] \[\frac{4x+25x}{200}=\frac{29}{5}\] \[x=\frac{29}{5}\times \frac{200}{29}\] \[x=40\]kmYou need to login to perform this action.
