What is the range of f(x) = (three-fourths) superscript x – 4?
{y | y > –4}
left-brace y vertical line y greater-than three-fourths right-brace
{y | y < –4}
left-brace y vertical line y less-than three-fourths right-brace

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
