Habib uncle has a furniture shop of next to Sarjeena's house. In his shop, there is a log of length 12frac(3)(5) m. He, cuts off 4frac(1)(5) m. of the log and keeps it apart. He divided the remaining portion of log into 3 equal parts, with 3/7 parts of one of three parts, he decided to make small wooden things. Let us calculate, what lenght of log he will use to make those small things. Firstly, let us find out, what lenght of log left when 4ꟷ1/5 m is out off.

A motor car covers (1)/(3) part of total distance with velocity v_(1) = 10 "km.h"^(-1) , the second (1)/(3) part with velocity v_(2) = 20 "km.h"^(-1) and the rest with velocity v_(3) = 60"km.h"^(-1) . What is the average speed of the car?
