The distance traveled by an object divided by the time it takes to travel that distance is called

Speed

Explanation:

- Speed is a scalar quantity that represents the rate of change of distance. It is calculated as

where

d is the distance travelled by the object (regardless of its direction)

t is the time elapsed

The speed is measured in meters per second (m/s). We can also notice that speed is different from velocity: in fact, speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude+direction).

the average speed is 24.57 km/hr

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )
