Select the property that allows the statement 10 = y to be written y = 10. commutative - addition distributive associative - multiplication symmetric commutative - multiplication associative - addition identity - addition

If a = b , then b = a

It's symmetric property of equality.

symmetric (if 10 = y, then y = 10)

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
