  • B 8.4 km/hr
  • C 11.05 km/hr
  • D 16.07 km/hr
Correct Answer: Option C

Explanation


To solve this problem, you can use the formula "speed = distance/time" to find the speed of the car.

The distance traveled is 800 meters, and the time taken is 260 seconds. Plugging these values into the formula gives us: speed = 800 m / 260 s = 3.07 m/s.

To convert the speed from m/s to km/hr, you can multiply it by (18/5). This gives us: 3.07 m/s * (18/5) = 11.05 km/hr.
