* Constant speed means the object covers the same amount of distance in every unit of time.
* Direct proportionality means that if one quantity increases, the other quantity increases at the same rate.
Example: If a car travels at a constant speed of 60 miles per hour, it will cover 60 miles in one hour, 120 miles in two hours, and so on. Notice how the distance traveled increases directly with the time spent traveling.
Formula: This relationship is captured by the formula:
Distance = Speed x Time
* Distance: The total length covered by the object.
* Speed: The rate at which the object covers distance (e.g., miles per hour, kilometers per second).
* Time: The duration of the object's motion.
In summary:
* When an object moves at a constant speed, the distance it covers is directly proportional to the time it travels.
* The formula Distance = Speed x Time allows you to calculate any of these values if you know the other two.
