Calculating Average Speed:

Step 1: Calculate the total distance traveled by Anjali:
- Distance traveled at 30 km/h: 15 km
- Distance traveled at 10 km/h: 25 km
- Total distance = 15 km + 25 km = 40 km

Step 2: Calculate the total time taken for the entire journey:
- Time taken to travel 15 km at 30 km/h: 15 km / 30 km/h = 0.5 hours
- Time taken to travel 25 km at 10 km/h: 25 km / 10 km/h = 2.5 hours
- Total time taken = 0.5 hours + 2.5 hours = 3 hours

Step 3: Calculate the average speed:
- Average speed = Total distance / Total time taken
- Average speed = 40 km / 3 hours = 40/3 km/h
Therefore, Anjali's average speed for the entire journey is 40/3 km/h. So, the correct answer is option 'A'.
