  • C 3 minutes
  • D 4 minutes
Correct Answer: Option D

Explanation


Given that the bus covers a distance of 60 kilometers in an hour when it stops at bus stops and a distance of 65 kilometers in an hour when it does not stop at bus stops, 

we can calculate the time taken to cover 5 kilometers as follows:

Time = distance/speed = 5 km / (65 km/hr - 60 km/hr) 

= 5 km / 5 km/hr 

= 1/15 hour 

= 1/15 * 60 minutes 

= 4 minutes.
