Agiraffe can travel 800 feet in 20 seconds. write a direct variation equation for the distance traveled in any time

The direct variation equation is:

d=kt

d is the distance the giraffe traveled
k is the constant of variation 
t is the time

800=k(20)
d=40t
ck
d=40t
800 ft= 40*20 ft
800 ft= 800 ft

Hope this helps bye!

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
