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

I'm hoping he meant an easy way to calculate it in his head... There are 60 minutes in an hour. So 98kts is just a little over 1.6kts per minute x 2 then add .5 which equals 4. Close enough for doing the calculations in your head.
