How far will an aircraft travel in 2-1/2 minutes with a groundspeed of 98 knots?

To calculate the distance an aircraft will travel, you can use the formula:

Distance = Speed x Time

However, in this case, the speed is given in knots (nautical miles per hour) and the time is given in minutes. So, we first need to convert the time from minutes to hours since a knot is a unit of speed expressed in nautical miles per hour.

Here are the steps:

1. Convert Time to Hours: There are 60 minutes in an hour. So, to convert 2-1/2 minutes (or 2.5 minutes) to hours, you would divide 2.5 by 60. This equals approximately 0.04167 hours.

2. Calculate Distance: Now, you can use the formula. Multiply the speed (98 knots) by the time in hours (0.04167 hours).

   Distance = 98 knots x 0.04167 hours = approximately 4.083 nautical miles

So, an aircraft with a groundspeed of 98 knots will travel approximately 4.083 nautical miles in 2-1/2 minutes.
