A bus between Vijayawada and Hyderabad passed the 100 km,160-km and 220-km points at 10.30 a.m., 11.30 a.m. and 1.30 p.m. Find the average speed of the bus during each of the following intervals:
(a)10.30 a.m. to 11.30 a.m. (b)11.30 a.m. to 1.30. p.m., and (c)10.30 a.m. to 1.30 p.m.

Explanation

To solve the problem, we need to find the average speed of the bus during three different intervals of time. The average speed is calculated using the formula:

\[ \text{Average Speed} = \frac{\text{Total Distance Covered}}{\text{Total Time Taken}} \]

Let's break down the solution step by step for each interval:
