Question 71648: A giraffe can travel 800 feet in 20 seconds. Write a direct variation equation for the distance traveled in any time.
Help, written problems are so hard for me. Answer by ptaylor(2198) (Show Source):
You can put this solution on YOUR website!
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
