Anita travelled a distance for 11 minutes at a speed of 35 km/h in an autorickshaw. She travelled for another 11 minutes in a taxi at 55 km/h and finally, she travelled for 11 minutes by bus at 42 km/h to reach home. Find her average speed for the whole journey.

Solution & Step-by-step Explanation

When a person travels for equal time intervals at different speeds (v_{1}, v_{2}, v_{3}), the average speed is simply the arithmetic mean of those speeds.Given: t_{1} = t_{2} = t_{3} = 11 minutes v_{1} = 35 km/h, v_{2} = 55 km/h, v_{3} = 42 km/h $ Average Speed = \frac{v _{1} + v _{2} + v _{3}}{3} $ Average Speed = \frac{35 + 55 + 42}{3} = \frac{132}{3} = 44 km/h
