An object on a number line moved from x = 15 cm to x = 165 cm and then moved back to x = 25 cm, all in a time of 100 seconds. What was the average velocity of the object?
What was the average speed of the object?

I GAVE THE ANSWER D0WN BELOW iM ASKING IF YOU WOULD SHOW OR EXPLAIN THE WORK FOR THE ANSWER (I WILL MAKE BRAINLIEST)

Δx/Δt = 10cm/100s = 0.1 m/s
Δx/Δt = (165-15cm) + (165-25) / 100s = 290 cm / 100s = 2.9 cm/s
