What is the answer

Question

While John is traveling along a straight interstate

highway, he notices that the mile marker reads

234Am. John travels until he reaches the 131Am

marker and then retraces his path to the 161/m

marker. How far has he traveled?

Answer 1

234-131 = 103

161-131 =30

103+30 = 133 That's the distance he traveled.

If it's asking for Displacement, it is final position - initial position. 161 - 234 = -63
