Question
A dragster moves at a speed of 225 miles per hour. Express this speed in nanometers per Microsecond.
Ok so I've solved this problem like twenty times, each time adding something into the equation or taking something out and I almost got the correct answer, but I was three decimals short. I have looked at this from every angle possible and still haven't figured out the answer.
225mi/hr x 1hr/60min x 1min/60sec x 1sec/1,000,000Msec x 1.609344x10^12nm/1mi = 3.621024x10^14/3600000000 = 100584
This is how i solved it, but its supposed to be 100.625 i don't understand how you get that??

You are correct. If it were m/s, 100.625 would be correct also.

So how would i get 100.625 nm/Msec?
