Answer:

Proportionality constant = \frac{1}{5}

Step-by-step explanation:

From the graph attached,

Data set representing the relation between seeing lightning and the hearing thunder is,

{(15, 3), (25, 5), (35, 7), (45, 9)}

Since, Distance from lightening (d) ∝ Time between lightening and thunder (t)

d = kt

Here k = proportionality constant

k = \frac{d}{t}

From the data set one point is (15, 3).

k = \frac{3}{15}

k = \frac{1}{5} miles per second

Therefore, proportionality constant is \frac{1}{5} miles per second.
