Answer:
v = 72 km/h
Step-by-step explanation:
Given that,
The distance between school a and b is 360 km.
A bus leaves school a at 9:30 and reaches school b at 2:30
Total time, t = 5 hours
We know that, the speed of an object is equal to the total distance divided by total time taken.
So,
v = d/t
[tex]v=\dfrac{360\ km}{5\h}\\\\v=72\ km/h[/tex]
So, the required speed is 72 km/h.
