Answer:
v = 48 km/hr
Step-by-step explanation:
Given that,
A circus van moves 50 km east in the first hour, 40 km west in the second hour, and 30 km north in the next half hour.
We need to find the average velocity of the travelling circus van.
Total distance covered = 50 km + 40 km + 30 km = 120 km
Total time = 2.5 h
Average speed = distance covered/time taken
So,
![v=(120\ km)/(2.5\ h)\\\\=48\ km/h](https://img.qammunity.org/2022/formulas/physics/college/69x03a7eao0uvu58kqv84t4iko1hkmicog.png)
So, the average velocity of the travelling circus van is equal to 48 km/hr.
