Answer:
F. 4h ≥ 18
Step-by-step explanation:
In 1 hour, she walks 4 miles.
In h hours, she walks 4h miles.
She wants to walk at least 18 miles. That means she wants the distance she walks to be 18 miles or greater.
4h ≥ 18
Answer: F. 4h ≥ 18
Ken's distance is: d(t)=1.7t
Ken's shadow is:
(14-6)/d(t)=14/s
8/d(t)=14/s
s=14d(t)/8
s=1.75d(t) and using the value for d(t) we have:
s=1.75(1.7t)
s=2.975t and if you want it in terms of d, d=1.7t, t=d/1.7 so
s=2.975(d/1.7)
s=1.75d
