Answer: If the T is 1.2 miles from the pen, and the turtle is 1.6 miles away from the T. If this are in a straight line, then you only need to add the distances, so the turtle need to walk the 1.6 miles to reach the "T", and then walk another 1.2 miles to reach his pen, so the total amount is 2.8 miles. But you only know that the pen is 1.2 miles from the "T", so the pen actually could be in the same pat that tommy is walking, so the distance would be only 1.6 miles - 1.2 miles, so the distance will be 0.8 miles.
So there are two options.
