what is the unit ni/sec??

hi...
someone had ask me what is the unit ni/sec means? and i search through the net but i can't find it. i found something like grams Ni/sec but this Ni=Nickel. and i also came across the below:
"You are traveling at a speed of 15 ni/sec. Your destination is 315 metersaway. How long will it be before you arrive at your destination?"

so can anyone help me and let me know if you know what actually is ni/sec??

1.Where did u see such problem...?If it's a book,doesn't it have a table of units and conversions to SI-mKgs...?
2.It may be a typo in the book.Perhaps it's "mi" apud "miles"...
3.Rats,i cannot think of another reasonable explanation...

Maybe it's just m/s. Sometimes, a written 'm' might be mistaken for an 'ni'.

That's a typo. There is no other possible explanation. The question is physics 10 level.

Edit: And you can be pretty sure it isn't a typo for miles! 15 mi/s the person will be there in like .05 seconds!

:rofl:

You're right,Cepheid,there are horses which can sustain 15m/s on 315m...

"6.You are traveling at a speed of 15 ni/sec. Your destination is 315 metersaway. How long will it be before you arrive at your destination? (3 points)"

It would assume that "m/sec" was intended since the distance is given in meters. Of course, that makes the problem trivial. It is possible that "in/sec" was intended and the problem is really to convert from inches to meters (or vice-versa).
