Answer
class CarData:
def __init__(self):
self.speed = 0.0 # Speed in mph
self.accelerator = 0 # Accelerator percentage
self.brake = 0 # Brake percentage
self.seatbelt = False # Seatbelt status
Step 3
Using a programming language of your choice, define the variable which can store the details of the 200 readings.

Answer
Initialize max_speed to 0.
Loop through each reading in readings.
If reading.speed > max_speed, then:
Set max_speed to reading.speed.
End Loop.
Return max_speed.
