# Easy Time, Speed & Distance Solved QuestionAptitude Discussion

 Q. A car driver driving in fog, passes a pedestrian who was walking at the rate of 2km/h in the same direction. The pedestrian could see the car for 6 min and it was visible to him up to a distance of 0.6 km. The speed of the car would be :
 ✔ A. 8 km/h ✖ B. 800 m/h ✖ C. 200 m/h ✖ D. 15 km/h

Solution:
Option(A) is correct

Traveller distance in 6 min = $\dfrac{2}{60}\times 6=\dfrac{2}{10}$

Total distance in 6 min = $\dfrac{2}{10}+\dfrac{6}{10}=\dfrac{8}{10}$

Speed =$\dfrac{8}{10}\times 10$

8 km/hr

Relative Speed = Distance / Time

Let speed of car be x

x - 2 = 0.6 / (6/60)

x - 2 = 0.6/0.1

x = 6+2

x = 8
