Answer 2

The average speed for the entire trip is 50 km/h.

Explanation:

Given that,

Suraj drives first 120 km in 2 hrs and next 180 km in next 4 hrs. We need to find the average speed of Suraj for the entire trip. We know that the total distance covered per unit time is called average velocity of an object. Here, total distance covered is, 120 km + 180 km = 300 km and the total time taken is, 2 hrs + 4 hrs = 6 hrs.

Average speed of Suraj is :

$v=\dfrac{d}{t}\\\\v=\dfrac{300\ km}{6\ h}\\\\v=50\ km/h$

So, the average speed for the entire trip is 50 km/h. Hence, this is the required solution.
