the most appropriate answer is C !!
as speed = dis/time ...so , 100/20

For this case we have that by definition:

\(s = \frac {d} {t}\)

Where,

  • s: speed
  • d: distance
  • t: time

We have then:

\(d = 100 m\\t = 20 s\)

Therefore, replacing values we have:

\(s = \frac {100} {20}\)

Answer:

An expression that calculates the speed in meters per second of an object that travels to distance of 100 m every 20 s is:

\(s = \frac {100} {20}\)

option C
