Use the image to answer the question.
An illustration shows a line chart titled Michael’s Reading Chart in quadrant 1 of the coordinate plane. Time in hours is labeled on the x-axis from 0 to 8 in increments of 2 and pages read on the y-axis from 0 to 400 in increments of 100. A curved line is drawn through quadrant 1. The approximate coordinates of points on the line are as follows: left parenthesis 0 comma 25 right parenthesis, left parenthesis 2 comma 50 right parenthesis, left parenthesis 4 comma 125 right parenthesis, left parenthesis 6 comma 175 right parenthesis, and left parenthesis 8 comma 240 right parenthesis.
Michael is participating in a summer reading challenge. He is logging the number of pages he can read over the course of several hours. The results are shown in the graph. Approximately how many hours did it take Michael to read 150 pages? Round to the nearest whole number.
(1 point)
Based on the information given, it can be determined that at 4 hours, Michael read 125 pages. The next data point, at 6 hours, shows that Michael read 175 pages. Using these two data points, it can be estimated that for every 2 hours, Michael reads an additional 50 pages (175-125 = 50).
To find out how many hours it took Michael to read 150 pages, the difference between 150 and 125 is calculated: 150 - 125 = 25.
Since every 50 pages represents 2 hours, the remaining 25 pages represent 1 hour.
Therefore, it took Michael approximately 5 hours to read 150 pages.
