In the case of 4 miles per hour (mph), it means that an object or person is covering a distance of 4 miles in one hour.

B. Calculation of speed

To calculate the speed of an object, we divide the distance traveled by the time taken. For example, if a person walks 4 miles in 1 hour, the speed can be calculated as 4 miles divided by 1 hour, which equals 4 mph. Speed can be measured in various units, such as meters per second (m/s), kilometers per hour (km/h), or miles per hour (mph), depending on the context.

C. Factors affecting speed

There are several factors that can affect the speed at which an object can travel. These include the physical capabilities of the object or person, the terrain or environment in which the object is moving, and external forces such as friction or air resistance. For example, if a person is walking uphill, their speed is likely to be slower compared to walking on a flat surface. Similarly, if a cyclist is riding against a strong headwind, their speed will be reduced due to the resistance caused by the wind.

Understanding these factors is important because they help explain why different modes of transportation have different maximum speeds. For instance, a car is capable of traveling much faster than a person walking due to its mechanical power and reduced effects of external forces.
