Which expression calculates the speed in meters per second of an object that travels a distance of 40 m every 10 s?



40 + 10​​


10 ÷ 40​​


40 ÷​ 10​


40⋅10

Verified Answer :

the answer would be 40/10

For this case we have that by definition:


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

Where,

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

Therefore, we have then:

\(d = 40m\\t = 10s\)

Thus, replacing values we have:

\(s = \frac {40} {10}\)

Answer:

An expression that calculates the speed in meters per second of an object that travels to distance of 40 m every 10 s is:

\(s = \frac {40} {10}\)
