An athlete runs M miles in 4 hours, then rides a bike N miles in the same number of hours. Which of the following represents the average speed, in miles per hour, for these two activities combined?
","rationale_html":"M + N / 8
formular for avg speed is total distance / total time
Time spent running = 4 and the time spent biking = 4
total time is 4 + 4 = 8
Total distance is M+ N
Thus A
