<PRE><B>Question 429990</B>
 Aircraft speed is calculate in nautical Miles per hour or knots. Two aircraft are flying in same direction. Aircraft A is flying at 210 miles per hour and Aircraft B at 330 Knots. At 1000hrs both aircraft are 75 nautical miles. At what time will a distance of 12 nautical miles exits between the two aircraft?
------------------------
1 mph = 1 statute mile/hour = 5280 ft/hour
1 knot = 1 nautical mile/hour = 6080 ft/hour
They are not the same thing.
1 knot =~ 1.15 mph
-------------------
&quot;At 1000hrs both aircraft are 75 nautical miles.&quot;  What does that mean?

Whoever wrote this problem needs to learn some things, and try again.
