the car travels one fourth of the distance on a straight road with a velocity 12 kilometre per hour the next 142 Velachery 24 kilometre per hour the next 14 February 24 kilometre per hour and the last one fourth velocity 40 km per hour what is the average velocity of the car for the entire journey
Answers
The average velocity of the car for the entire journey, if 1/4th of whole distance with 12 km/hr, next 1/4th with 24 km/hr, next 1/4th with 24 km/hr and last 1/4th distance with 40 km/hr, is 5.21 km/hr.
Explanation:
Required Formula:
Average Speed =
It is given,
The velocity for the first 1/4th of the distance = 12 km/hr
The velocity for the next 1/4th of the distance = 24 km/hr
The velocity for the next 1/4th of the distance = 24 km/hr
The velocity for the last 1/4th of the distance = 40 km/hr
Let’s assume the total distance covered during the entire journey is “d” km.
So,
The time for the first 1/4th journey = hr
The time for the next 1/4th journey = hr
The time for the next 1/4th journey = hr
The time for the last 1/4th journey = hr
Now, substituting the values in the above-required formula, we get
Average Velocity
=
=
=
=
= 5.21 km/hr
Thus, the average velocity of the car for the entire journey is 5.21 km/hr.
