Continuous velocity exercises

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!

For a start, what have you tried so far? Where are you stuck?

How many per minute?

How many meters per minute?

What did you get when you divided?

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

Hint: Convert the minutes to a decimal portion of an hour. Then divide.

Re: Continuous velocity exercises

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

Re: Continuous velocity exercises

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

Re: Continuous velocity exercises

Hi;

No need to close it.


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

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

Re: Continuous velocity exercises

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.

Re: Continuous velocity exercises

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