Easy question! Miles per hour?

Question

Hey! Are we allowed to write miles per minute on something? Please answer only if you know because this is for an important grade! I just want to know if we can write m/m like we write m/h? :) thanks in advance!

Answer 1

You can write "mile per minute" or "mile/minute"--why not?  

When using abbreviations you need to define them.  If "m" can mean either mile or minute there is ambiguity.

Mile per 36 second or m/(36s) can be useful for a quick approximation of groundspeed in knots:  4.8 mile => 480 knot.

Answer 2

Well, in mission planning miles/minute is used extensively.  It's an easy way to calculate backwards from times-on-target, and Air Refueling Contact Times to name two. If you clearly labeled your work as Miles/minute and not "m/m" I'm sure you'll be fine.

Answer 3

yes you can

Answer 4

I don't think so..

Answer 5

I don't think there is a problem with doing this, but speeds are almost never noted in miles per minute. If this is for a grade, I would check with the teacher or professor to find out if it is acceptable.

Answer 6

Only if your going to break it down into decimal points. You would have to go 120 miles per hour to write two miles a minute. So 75 miles per hour would be 1.15 or something like that.
