Find the time it takes to travel 30 km/hr for a bus which accelerates uniformly from 40 km/hr to 80 km/hr .
------------
30 km/hr is not a distance.
---
Accelerates over what distance, or for how much time?
---
If you mean from 40 km/hr to 80 km/hr over 30 km, its average speed is 60 km/hr
--> 0.5 hours
