Question

If it takes Ashley 3 seconds to run from the batter's box to first base at an average speed of

6.5 meters per second, what is the distance she covers in that time?

Answer 1

19.5 meters.

Step-by-step explanation:

Hey! Let's help you with your problem there!

So, what we know is that it takes Ashley 3 seconds to run from the batter's box to first base and that she was running at an average speed of 6.5 meters per second. Let's figure this out!

To start, we're going to take the average speed here. We can write that as:

`6.5m/s`

Now, this is the average speed. Notice how it is in the unit meters per second. The "per" in this case refers to how many meters she ran in one second! So, since we're trying to find the distance that she covers within 3 seconds, we can take the 6.5 meters per second and multiply that by 3 like so!

`(6.5m/s)*3`

`=6.5*3`

`=19.5`

And there we have it! Ashley ran 19.5 meters in 3 seconds from the batter's box to first base!

If you want it in a more scientific way, we can say that
`Velocity = (distance)/(time)`, we already know the velocity (6.5 meters per second or 6.5m/s) and we know the time (3 seconds), we just need to rearrange the formula to solve for distance and that would be:

`Distance = Velocity * Time`

We plug in the numbers and it would still give us the same answer!
