Question

An object travels 15m in 3 s. What is it's speed?

Answer 1

Answer:

5 m/sec

Explanation:

speed = distance / time

           = 15m / 3sec

           = 5 m/sec

Answer 2

Answer:

5 m/s

Explanation:

The equation for speed is distance/time. The distance, 15, will go over the time, 3. So, we have 15/3.

You can simplify this by dividing both sides by 3. 15/3 is 5. 3/3 is 1. Now we have 5/1, with 5 as meters, 1 and second.

Therefore, the correct answer is 5 m/s.
