calculates speed, distance, time

• speed - the rate of change of position or distance travelled by an object or person
• speed = distance travelled divided time taken
• distance - the distance between two points on a line is the length of the line that joins them
• distance = time taken x speed
• time - the length of time that a wave travels from one point to another
• time = distance divided by speed (s)
