Answer:
y=5/1 - 3
Step-by-step explanation:
use rise over run
To find this we need to subtract July rainfall (8.35) and Octobers rainfall (3.87) which equals 4.48.
The direct variation equation is:
d=kt
where d is the distance that the giraffe travels
k is the constant of variation
and t is time
Now we are told that the giraffe can travel 800 ft in 20 seconds, so we can solve for the constant of variation (k)
800=k(20) divide both sides by 20
k=40-------------and the units are ft per sec
So now we can write
d=40t
ck
d=40t
800ft=40*20 ft
800 ft= 800 ft
Hope this helps!
