Question 1：(please use function that return a value)
Write a program to display information to a driver based on his/her speed according to the following table:
|km/h over the limit||Fine|
|1 to 20||$100|
|21 to 30||$270|
|31 or above||$500|
Sample Input 1: Enter the speed limit: 40 Enter the recorded speed of the car: 39 Sample output 1: Congratulations, you are within the speed limit!
Sample Input 2: Enter the speed limit: 100 Enter the recorded speed of the car: 131 Sample output 2: You are speeding and your fine is $500
Question 2：(please use function that return a value)
You know a family with three children. Their ages form an arithmetic sequence: the difference in ages between the middle child and youngest child is the same as the difference in ages between the oldest child and the middle child. For example, their ages could be 5, 10 and 15, since both adjacent pairs have a difference of 5 years.
Given the ages of the youngest and middle children, what is the age of the oldest child?
The input consists of two integers, each on a separate line. The first line is the age Y of the youngest child. The second line is the age M of the middle child . The output will be the age of the oldest child.
Sample Input 1: Age Y: 12 Age M: 15 Sample output 1: Age O: 18
Sample Input 2: Age Y: 10 AgeM: 10 Sample output 2: Age O: 10

sl = int(input(‘speed limit: ‘))
rs = int(input(‘recorded speed: ‘))
sl – rs = otl
if otl <= 20:
fine = 100
if otl = 30:
fine = 500
if sl >= rs:
if sl <= rs:
print('you can not get away with it')
the otl is not defined
