Finch Assignment 9  Travel
You are going to add more functions to your module.
Attach a pen to the Finch's tail. Program the Finchto go forward for 1 or more seconds.
Measure the length of the line it draws. Use this to calculate cm/s.
Write a function travel(distance) to make the robot travel the given distance. Use cm as your units.
In other words, when you call the function travel, you add the distance you want the Finch to travel
inside the parentheses.
That number will be stored in
the variable distance, and the Finch must be programmed to do the calculation to convert the
input distance into the correct time for it to travel at that speed.
You know how far the Finch travels in one second 
calculate how many seconds it should travel to go the distance required.
Test the function on the robot a few times to see how accurate the line is.
Turn the program in to EETT2  Pereira  AI 201x  Python assignments as travelyourname then add it to your library module.
For extra credit, use speed as well as distance as variables.
Write a Reflection on what you have learned.
