# A classical mechanics problem by Sharad Roy

**Classical Mechanics**Level pending

A car moves from Village **A** to Village **B** with a speed of **30 kmph**. After it reaches village **B**, it takes a **U**-turn and starts heading to village **A**. It travels half of its time with a speed of **25 kmph** and other half with a speed of **20 kmph**. Find the **average speed** of the car during the whole journey?

**Note:** Speed of car is uniform when it travels from village **A** to **B**, while when it is heading back to Village **A** from **B** its speed's are different i.e. **20 kmph** and **25 kmph**. You need to find average speed of car during the **whole journey**.

**Your answer seems reasonable.**Find out if you're right!

**That seems reasonable.**Find out if you're right!
