The first thing we need to do is the math inside the parentheses:

(1 + 1/3) = 1 + 1/3 = 4/3

Next, we square the parentheses:

(4/3)² = 16/9

Now, all we need to do is subtract!

16/9 - 2/9 = 14/9

If you need to make it a proper fraction, your answer is 1 5/9, but if you leave it improper then 14/9.

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
