• Speed is a scalar quantity that describes "the rate at which an object moves." The rate at which an object travels over a given distance is known as speed.

• Distance is a numerical representation of the distance between two objects or points.

• The average speed of something is determined by dividing the total distance traveled by the total time it took to travel that distance. Average speed refers to the speed at which a vehicle travels over the course of a journey.

• Speed is calculated using the formula speed = distance x time. You'll need to know the units for distance and time to figure out what the units for speed are. Since the distance is measured in metres (m) and the time is measured in seconds (s), the units would be metres per second (m/s).

• Pythagorean theorem application. To find the distance between any two lines, rewrite the Pythagorean theorem as d=((x 2-x 1)2+(y 2-y 1)2.

• To find the time, use the formula t = d/s, which equals time divided by distance divided by speed.
