Answer:
180°
Explanation:
You are starting at 125° W and ending at 55° E.
It might be easier to find the distance travelled by using a number line.
Numbers west are negative and numbers east are positive.
Start at -125 and go in jumps of 10 until you reach +55.
You make 18 jumps of 10° each for a total of 180°.
You have travelled a distance of 180°.
What you have just done is equivalent to saying:
distance travelled = end - start = 55° - (-125°) = 55° + 125° = 180°
