### Instruction: A trained covered x km at 30 kmph and another 2x km at 20 kmph. Find the average speed of the train in covering the entire 3x km.
Answer Choices: (A) 20kmph (B) 22.5kmph (C) 25kmph (D) 30kmph (E) 35kmph Please respond by writing a program in Python.### Response: # The average speed is total distance divided by total time. 
# The total distance is 3x km. 
# The time to cover x km at 30 kmph is x/30 hours. 
# The time to cover 2x km at 20 kmph is 2x/20 = x hours. 
# So, the total time is x/30 + x = 4x/3 hours. 
# Therefore, the average speed is 3x / (4x/3) = 22.5 kmph.
average_speed = 22.5
