Classes: Exercise 2
Write a function called mul_time that takes a Time object and a number and returns a new Time object that contains the product of the original Time and the number.
Then use mul_time to write a function that takes a Time object that represents the finishing time in a race, and a number that represents the distance, and returns a Time object that represents the average pace (time per mile).
