Answer:
C. 5 km/h north
Step-by-step explanation:
Speed is the rate at which an object changes position, and it is measured in meters per square seconds. The formula or equation used in calculating speed is distance divided by time. The distance traveled is always in meters and time is always in seconds to get the speed it will be one meter per second. Speed doesn’t specify the direction at which an object will travel. Hence the answer is C. 5Km/hr north
