Well, there are many velocity formulas, but let us focus on this formula :

distance

velocity = -----------

time

Let's start.

**How many per minute?**

1) Distance = 500 meters and Time = 15 minutes

How many meters per minute?

2) Distance = 88 kilometers and Time = 4 minutes and 40 seconds

How many kilometers per minute?

3) Distance = 17.5 kilometers and Time = 3 minutes

How many kilometers per minute?

**How many per hour?**

4) Distance = 117 kilometers and Time = 9 hours

How many kilometers per hour?

5) Distance = 975 meters and Time = 1 hour and 20 minutes

How many meters per hour?

6) Distance = 400 miles and Time = 1 day

How many miles per hour?

More items soon, wait for them and please answer them!

I will have a name change soon. By the way, welcome to the Philippines, Pope Francis!

What portion of a minute is forty seconds? What did you get when you divided?

Since it is in the Exercises section, I would presume he meant for us to solve it for practice.

1 small thing by the way. Velocity is displacement over time.

Hi;

No need to close it.

**In mathematics, you don't understand things. You just get used to them.**

**I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.**

To close it there would have to be some trouble in it or no replies by other posters.

Hi; I apologize for making you think I wanted to get this thread closed. I simply told you to make a slight change in the original post sice velocity is a vector.

What vector? I don't know much about it.
