Final answer:
Peru is predominantly located to the west of the 60° W meridian, although a small part of the country does extend east of this line.
Step-by-step explanation:
Peru is located predominantly to the west of the 60° W meridian. The 60° W meridian passes through South America and is used as a reference line to determine the geographical position of places relative to the Prime Meridian. Since the majority of Peru's territory lies west of this meridian line, when referring to the relative position of Peru to the 60° W meridian, it is accurate to say it is west. However, a very small part of Peru does extend east of the 60° W meridian, but for the purpose of elementary understanding, the country is commonly referred to as being west of the meridian.
