Question

1. The class social committee, consisting of 6 people, is planning a party. The committee wants to have a cake for the group. If each cake provides 24 servings, how many cakes should the committee order to serve a class of 70 and staff of 3?

2. Young adult female is running a 24-mile course. If she runs the first 6 miles in one hour, the second 6 miles in 1.2 hr., the third 6 miles in 1.5 hr. and the fourth 6 miles in 1.6 hr. How ling will it take her to complete this 24 miles run?

Answer 1

73/24 = ______ cakes (round up)


1 + 1.2 + 1.5 + 1.6 = ?

Answer 2

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.
