(Requires technology.) The accompanying table shows the calories per minute burned by a 154- pound person moving at speeds from 2.5 to 12 miles/hour (mph). (Note: A fast walk is about 5 mph; faster than that is considered jogging or slow running.) Marathons, about 26 miles long, are now run in slightly over 2 hours, so the top distance runners are approaching a speed of 13 mph. a. Plot the data. b. Does it look as if the relationship between speed and calories per minute is linear? If so, generate a linear model. Identify the variables and a reasonable domain for the model, and interpret the slope and vertical intercept. How well does your line fit the data? c. Describe in your own words what the model tells you about the relationship between speed and calories per minute.
