We here on Open study are not here to help people cheat on there tests, I'm sorry. :c If you need help with actually learning something we will be glad to help you! :)

Cheating on tests, spamming, and things of that manor can get you into trouble by your school, and the moderators because these things break the code of conduct. Good luck though! :)

An airplane travels at an average speed of 250 mph for 3 hours. How far does the airplane travel?

whpalmer4 · Answer

rate equation is:

$$x = r t$$where $x$ is the distance, or amount,
$r$ is the rate
$t$ is the time

Here you have $r = 250 \text{ miles/hour}$, $t = 3\text{ hours}$

Plug them in to the rate equation and you'll get an answer with units of $\text{ miles}$ after cancelation

It is useful to do your problems with the units attached so that the units serve as a check that you have set the problem up correctly and done any necessary unit conversions correctly.  If you don't, you'll get a weird unit and that's your tip-off that you need to hunt down your mistake(s).
