To find: The equation that relates for the given value of d and t also plot the graph.

Answer to Problem 25PPE
The equation
Explanation of Solution
Given information:
Distance, d = 13.2mile
Time to cover this distance, t= 1.25hr
Suppose d varies directly with t
And
An equation is known as direct variation if its equation is in the form of
The measure of the constant of variation is calculated by diving
Let the direct variation equation be
The equation
The graph of the equation as shown below:
