Question 1:

python programming, using python 3.

a) Write a function mh2kh(s) that given the speed, s, expressed in miles/hour returns the same speed expressed in kilometres/hour.

b) Two numbers a and b are called pythagorean pair if both a and b are integers and there exists an integer c such that a2 + b2 = c2. Write a function pythagorean_pair(a,b) that takes two integers a and b as input and returns True if a and b are pythagorean pair and False otherwise.

How the testing of the question looks like:

testing Question 1a) >>>

>>> mh2kh(5)

8.0467

>>> >>> mh2kh(110.4)

177.67113600000002

# testing Question 1b) >>>

>>> pythagorean_pair(2,2)

False >>> pythagorean_pair(6,2)

False >>> pythagorean_pair(6,8) True >>> pythagorean_pair(300,-400)

True
