What is 562937565x3745638738287.364648x6742 837483137460928371x4374974524682764 8792356485=

1.2651365e+22

You probably just typed in random numbers but anyway...

First we do 562937565x3745638738287.364648

The answer to that is 2.1085608e+21

Then we multiply

2.1085608e+21*6=1.2651365e+22

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

$12. that is my answer.
