A bus travelling the first one third distance at a speed of 10 km/h, the next one third at 20 km/h and the last one third at 60 km/h. The average speed (in km /h) of the bus is

Text Solution

AI Generated Solution

To find the average speed of the bus, we can follow these steps: ### Step 1: Define the total distance Assume the total distance traveled by the bus is \( S \). Since the bus travels in three equal parts, each part will be \( \frac{S}{3} \). ### Step 2: Calculate the time taken for each segment 1. **First segment**: The bus travels \( \frac{S}{3} \) at a speed of 10 km/h. \[ ...
