Answer:
A bus travels first 150 km with a speed of 30 km/h and next 60 km with a speed of 40 km /h. What is the average speed of the bus during the entire journey?
We know that, Speed = Distance / Time
So, time taken to travel first 150 km, t1 = Distance / Speed = 150 / 30 = 5 h
Time taken to travel next 60 km, t2 = Distance / Speed = 60 / 40 = 1.5 h
Total distance travelled = 210 km
Total time taken = t1 + t2 = 5 + 1.5 = 6.5 h
So, average speed = Total distance / Total time = 210 / 6.5 = 32.308 km/h
