The altitude y in feet of a hawk that is descending can be represented by the equation y = -20x + 350, where x represents the time in minutes. The equation y = -10x + 400 represents the altitude y in feet of an eagle after
descending x minutes.
Which bird is closer to the ground after 8 minutes?
The is closer to the ground.
How much closer?
feet.

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
