Statistics, Data Analysis and Probability K12There are 9 houses on a street. The distance between any two adjacent houses is the same.
There is 1 child living in house number 1, two children living in house number 2, and so on. Nine children live in the house number 9.

If the school bus can only make one stop on that street, in front of which house should the bus stop so that the sum of walking distance among all children will be minimum?
