1. If a cyclist travels at 9 km/hour what distance will he cover in 30 seconds?2. a) 75 m b) 7.5 m c)15 m d) 150 m3. My guess is that its 75 m.

It would be better to show that calculation rather than just saying "guess"!Ayesha Shafique said:Calculation.
To calculate distance and time, you need to use the formula: Distance = Speed x Time. This means that if you know the speed of an object and the time it has been traveling, you can determine the distance it has covered.
Speed and velocity are often used interchangeably, but they are not the same. Speed is a measure of how fast an object is moving, while velocity is a measure of how fast an object is moving in a specific direction. In other words, velocity takes into account both the speed and direction of an object's motion.
To convert units of measurement for distance and time, you can use conversion factors. For example, to convert from miles per hour to kilometers per hour, you can use the conversion factor 1 mile = 1.609 kilometers. Similarly, to convert from hours to minutes, you can use the conversion factor 1 hour = 60 minutes.
Average speed is the total distance traveled divided by the total time taken, while instantaneous speed is the speed at a specific moment in time. In other words, average speed gives an overall picture of an object's speed, while instantaneous speed gives a more specific and instantaneous measure.
The distance an object travels directly affects its time and speed. The greater the distance, the longer the time it will take to cover that distance, and the faster the speed, the shorter the time it will take to cover the distance. Additionally, changes in distance can also affect an object's speed, as a longer distance may require a change in speed to maintain a certain time.
