By definition we have to:
 d = v * t
 Where,
 d: distance
 v: speed
 t: time
 Substituting values:
 d (t) = 2.36t
 For t = 6 we have:
 d (6) = 2.36 * (6)
 d (6) = 14.16 feet
 Answer:
 a rule to describe the function is:
 d (t) = 2.36t
 the snail will travel 14.16 feet in 6 minutes
 C. d (t) = 2.36t; 14.16 ft
