Subtract the polynomials: (5x3 - 3x + 4) - (3x3 - 2x2 + 6x-1). Enter your answer as a polynomial in descending order below, and use the caret (1) for
exponents. For example, you would write 4x as 4x^2.

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

is there answer choices?
