A car covers `(1)/(3)` part of total distance with a speed of `20 km hr^-1` and second `(1)/(3)` part with a speed of `30 km hr^-1` and the last `(1)/(3)` part with a speed of `60 km hr^-1`. The average speed of the car is.

A car covers (1)/(3) part of total distance with a speed of 20 km h^(-1) and second 1 /3 and the last part with a speed of 60 km h^(1) The average speed of the car is:

Anoop travels first (1)/(3)rd of the total distance at the speed of 10 km/hr and the next (1)/(3)rd distance at the speed of 20 km/hr and the last (1)/(3)rd distance at the speed of 60 km/hr. The average speed of Anoop is :

A car travels the first one-third of a certain distance with a speed of 10 km/hr, the next one-third distance with speed of 20 km/hr and the last one-third distance with a speed of 60 km/hr. The average speed of the car for the whole journey is

In a journey, the first one - third of the distance is covered at a speed of 20km/hr, the second 1/3 at speed of 30 km/hrand the last 1/3 at a speed of 24 km/hr. The average speed in km/hr for the whole journey is

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?

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

A train runs of 2 hrs at the speed of 40 km/h and then runs for 4(1)/(2) hrs at the speed of 60 km/h and then the runs for 3(1)/(2) hrs, at the speed of 70 km per hour. Find the average speed of the train.
