2. Bicycle Ride An Investigation

3. Bicycle Ride A man is riding his bicycle on a road that can be thought of as having four parts of equal length. On the first part of his journey, which is level, he pedals at 10 kilometers per hour. On the second part, an upward slope, he goes 5 kilometers per hour. On the third part, a downward slope, he goes 30 kilometers per hour. On the last part, which is level again-but with the wind pushing him-he goes at 15 kilometer per hour? What is the man’s average speed for the whole journey?

4. Exercise:- A cyclist covers the first half of a journey at an average speed of V+10 km/hr and the second half of the journey at a speed of V-10 km/hr. Find his average speed for the whole journey.
