Which method correctly solves the equation using the multiplication property of equality and the reciprocal of One-third? One-third (x + 9) = negative 12 One-third (x + 9 = negative 12. One-third x + 3 = negative 4. One-third x = negative 7. x = negative 27. One-third (x + 9) = negative 12. x + 9 = negative 4. x = negative 13. One-third (x + 9) = negative 12. x + 3 = negative 12. x = negative 15. One-third (x + 9) = negative 12. x + 9 = negative 36. x = negative 45.

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
