Final answer:
The question pertains to the Physics concept of speed and involves converting between different units like km/h to m/s and m/s to mi/h, as well as calculating average speed from distance and time data.
Step-by-step explanation:
The subject of the provided question falls under Physics, specifically within the topic of kinematics which deals with speed, velocity, and acceleration. When discussing the speeds of a vehicle, converting between different units of speed is often required. For example, the speed limit on some interstate highways is roughly 100 km/h. This can be converted to meters per second (m/s) by dividing by 3.6 (since 1 km/h = 1000 m/3600 s). Thus, 100 km/h is approximately 27.78 m/s.
In another case, if a car is traveling at a speed of 33 m/s, we might want to express this in miles per hour (mi/h). To convert from m/s to mi/h, we can multiply by approximately 2.237 (since 1 m/s = 2.237 mi/h). Hence, 33 m/s is about 73.82 mi/h. Understanding these conversions and units is essential in Physics to analyze the motion of objects.
If we want to determine average speed, such as in the example studied, where a car travels 150 kilometers in 3.2 hours, we use the formula Vavg = distance / time which yields an average speed of 46.875 km/h, usually rounded to 47 km/h. Observing and calculating these speeds help us to connect theoretical knowledge with practical experiences, such as driving, and allow us to appreciate the implications of speed in our daily lives.
