To solve the problem step by step, we will first determine whether the motion of the car is uniform and then calculate the average speed of the car. ### Step 1: Determine if the motion is uniform - A motion is considered uniform if the speed remains constant throughout the journey. - In this case, the car travels 100 km at a speed of 50 km/h and then 200 km at a speed of 20 km/h. - Since the speed changes from 50 km/h to 20 km/h, the motion is **not uniform**. ### Step 2: Calculate the time taken for each part of the journey ...
