A question on a test asks students to find the speed at which a car travels. The graph shows a proportional relationship between the distance traveled in miles and time in hours. Billy incorrectly says that the speed of the car is 1/60 mile per hour. What is the speed of the car? What error might Billy have made?

Step-by-step explanation:

Since, speed of a car =

From  the graph attached,

A point (1, 60) lies on the line shown in graph.

At this point speed of the car =

                                                = 60 miles per hour

But Billy says the speed of the car is miles per hour.

So the error in the Billy's answer is that he has used the wrong formula to calculate the speed.

(As per Billy, speed = )
