Answer: The correct unit of speed is d) m/s.

Explanation: Speed is a measure of how quickly an object moves. It is calculated by dividing the distance traveled by the time taken. In the given options, "m/s" stands for meters per second, which is a unit of speed commonly used in sciences.

To understand this unit, let's break it down: "m" stands for meters, which is a unit of distance, and "s" stands for seconds, which is a unit of time. So, "m/s" means how many meters an object can travel in one second.

For example, if an object travels 10 meters in 2 seconds, its speed would be calculated as follows:

Speed = Distance / Time

= 10 meters / 2 seconds

= 5 meters per second

Therefore, "m/s" is the correct unit of speed
