In 6 minutes, the car goes ahead by 0.6 km. Hence, the relative speed of the car with respect to the
pedestrian is equal to 6 kmph, since, the pedestrian is walking at 2 kmph, hence, the net speed is 8
kmph.

A car driver, driving in a fog, passes a pedestrian who was walking at...
Given information:
- Speed of pedestrian = 2 km/h
- Time for which pedestrian could see the car = 6 minutes = 0.1 hours
- Distance up to which car was visible to pedestrian = 0.6 km

To find:
Speed of the car

Solution:
Let the speed of the car be v km/h.

Relative speed of car with respect to pedestrian = v - 2 km/h

Time for which car was visible to pedestrian = 0.1 hours

Distance up to which car was visible to pedestrian = 0.6 km

We know that,

distance = speed × time

=> 0.6 = (v - 2) × 0.1

=> v - 2 = 6

=> v = 8 km/h

Therefore, the speed of the car is 8 km/h.

Answer: d) 8 km/h
