Answer:
Time (secs) => distance (ft)
1 => ⅔
15 => 10
24 => 16
45 => 30
Step-by-step explanation:
Equation to represent this proportional relationship is , where,
t = time
d = distance
k = constant of proportionality
To complete the table, let's find k given that the turtles swarm 16 ft (d) in 24 secs (t).
Substitute d = 16, t = 24 into the equation.
(division property of equality)
Let's complete the table by substituting the value of k and the other given value of t or d, as the case may be:
For 1 sec, let's find distance (d):
d = ⅔ ft
For 10 ft, let's find the time (t) taken:
Multiply both sides by 3
Divide both sides by 2
t = 15 secs
For 45 secs, let's find distance (d):
d = 30 ft
