Step-by-step explanation:

The Olympic record for running the 200 m dash is 19.3 seconds. What is the average speed for this record?

A. 10.36 m/s

B. 3960 m/s

C. 219.3 m

D. 0.0965 m/s

speed is scalar quantity and hence as no direction but only magnitude. time and distance are also scalar quantity

200/19.3

speed=10.36m/s
