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

Respuesta :

the answer would be 40/10

For this case we have that by definition:

[tex]s = \frac {d} {t}[/tex]

Where,

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

Therefore, we have then:

[tex]d = 40m\\t = 10s[/tex]

Thus, replacing values we have:

[tex]s = \frac {40} {10}[/tex]

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:

[tex]s = \frac {40} {10}[/tex]
