Question

The line on this graph represents an in-line skater's distance traveled over time. From the graph, you can tell that the skater travels at a constant speed. What is the speed? (Hint: Dividing distance by time gives the speed, which is the same as the slope of the line.)

A). 10 mi/h B). 0.1 mi/h C). 25 mi/h D). 15 mi/h

Answer 1

The best answer to the problem given above would be letter A. The speed of the skater travels at 10 miles per hour constantly. I got this through employing the formula, y2 - y1 / x2 - x1 and computed using the points.

which is:

v = (25 miles -10 miles) / (2.5 hrs - 1 hrs)
v = 10 miles per hour

Thus, the answer is 10 miles per hour.
