Correct Answer: Option C

Explanation


The speed of the object is given as 12 m/s.

The time taken to travel a certain distance is given as 3 hours 45 minutes, or 3 3/4 hours, or 15/4 hours.

To find the distance traveled by the object, we can use the formula distance = speed * time. 

Plugging in the values given in the problem, we get distance = 12 m/s * 15/4 hours.

To convert the speed from meters per second to kilometers per hour, 

we can multiply it by the conversion factor 18/5. This gives us a speed of 12 * 18/5 = 21.6 km/hr.

Plugging the converted speed into the formula for distance, we get distance = 21.6 km/hr * 15/4 hours = 162 km.
