1. If each person gets 1 serving, then you would need to get 4 cakes, and have 23 servings left over. If you get 3 cakes, one person won't get any servings of cake, so you need 4 cakes.
2. For this one, you need the time it takes her to complete her 24-mile course, and those four different 6 mile periods take different amounts of time. However, if you add up those four 6 mile periods, it makes up the whole 24-mile course. So if you do likewise with the times it takes to complete the 6 mile periods, you get 1 hr. + 1.2 hr. + 1.5 hr. + 1.6 hr., which is 5.3 hrs.
