File comment: Hi Karishma,
I have a doubt regarding using the weighted average method in this question >> Why are we taking the ratio of time taken for the 2 trips as the ratio of weights in the w.avg question ?? why not the distance.
When we use the ratio of the distance as the ratio of weights we get the ans as 70 as inverse of the ratio of weights(1:1) == the ratio of the distance of data points away from the main average.
When we use the ratio of the TIME as the ratio of weights we get the ans as 75 as inverse of the ratio of weights(2:3) == the ratio of the distance of data points away from the main average.
