(5,6 linear )
(7,8 non linear)
Answer:
32 m
Step-by-step explanation:
Height of mast = 96tan30
Distance of second point = 96tan30 / tan60
Distance = 32 m
We can solve it two ways, we´ll do it via physics:
We know that:
d=vt
d=770km/h*15h
d=11550km
Now at 660km/h:
t=d/v
t=11550km/660km/h
t=17,5h
Math way:
770km/h→15h
660km/h→x
So:
(770*15)/660=x
x=17,5h
