Explanation / Answer

Given energy needed for 1 hr of running = 4.2*10^6

Energy given by 1 candy bar = 1*10^6

Energy required for five hours of running = 5 * 4.2 * 10^6

= 21 * 10^6

So number of candy bars have to eat = (21 * 10^6)/ (1* 10^6)

= 21

So the required answer is 21. So an adult would have to eat 21 average candy bars.
