Answer:
16.3 ft/s
Explanation:
Let d=distance
and
x = length of shadow.
Therfore,
x=(d + x)
= 6/15
So,
15x = 6x + 6d
9x = 6d.
x = (2/3)d.
As we know that:
dx=dt
= (2/3) (d/dt)
Also,
Given:
d(d)=dt
= 7 ft/s
Thus,
d(d + x)=dt
= (7/3)d (d/dt)
Substitute, d= 7
d(d + x) = 49/3 ft/s.
Hence,
d(d + x) = 16.3 ft/s.
