Answer:
By measuring an object's position at different times, you can determine the distance it travels. Suppose you are in a sprint race. At 6 seconds, you are 48 meters from the starting line. The 48 meters is the distance you traveled.
To know how fast you ran those 48 meters, we need to add another factor---time. By dividing the distance traveled by the amount of time it takes to travel that distance, we can determine the speed, or rate, that you ran.
Dividing 48 m by 6 seconds tells us that your average speed was 8 m per second.
Formula: Distance ÷ Time = Speed
To determine the distance a car travels, we multiply its average speed by the amount of time it travels. For example, a car going 100 km/h for 2 hours would travel 200 km.
Formula: Speed x Time = Distance
