Answer 2

Answer:

This is another simple “3 rule”

This is another simple “3 rule”Speed is distance per time or V = D/T

This is another simple “3 rule”Speed is distance per time or V = D/TYou wish to know the speed of your airplane 1st

This is another simple “3 rule”Speed is distance per time or V = D/TYou wish to know the speed of your airplane 1stX = 2695 /3.5

This is another simple “3 rule”Speed is distance per time or V = D/TYou wish to know the speed of your airplane 1stX = 2695 /3.5X= 770 KM/h

This is another simple “3 rule”Speed is distance per time or V = D/TYou wish to know the speed of your airplane 1stX = 2695 /3.5X= 770 KM/hNow you got the speed and distance but you wish to know the time, let’s do some algebra :
