The graph to the right shows the relationship between distance and time for a car that is similar to constant speed. 1) What is the velocity ?
2) Is it a function
3) If it is a function, write the rule to represent it
4.) Make a table for the function, and indicate 6 pairs of inputs / outputs​

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
