Distance=Speed*Time and all that...
A/C flying at 420knots, 70 miles between A+B, how long to cover that distance etc...
Looking confused... you'll be right at home here then
Now see, this is where i get annoyed at myself. Using my physics ie D=S*T, the sum is 70miles divide by 420kts (lets assume 420kts is also 420mph)
So the sum would be 70/420 = 0.16 =1/6th hour = 10 mins
Now thats allvery well with a calculator, but how to divide 70 by 420 in your head? Also, if the answer is 0.24, how to convert that into minutes in your head?
