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
