Which of theres is the correct unit for speed? a) m/s- meters per second b) j- joules c) n- newtons

Since the speed formula is = Distance / time

speed = distance /time

speed = metre/ seconds

speed = m/s

a) m/s- meters per second

Explanation:

Recall that m/s (meters per second) is the official derived SI unit for speed. That is, it is length (meters) over time (second), hence m/s.

It can't be joules (J), since that is the SI unit for work & energy.

It also can't be newtons (N), since that is the SI unit for force.

Therefore, the correct answer is a) m/s- meters per second.

I hope this made sense to you, if not, feel free to let me know and I can try to provide further assistance.
