Answer:

72 km

Explanation:

We are given that

John marker reads=239 km

John travels and reaches the marker=149 km

John retraces his path and reaches the marker=167 km

We have to find the John's resultant displacement from 239 km.

Displacement:The displacement is the distance between two positions.

By definition of displacement

John's resultant displacement from 239 km=239-167

John's resultant displacement from 239 km=72 km

Hence, John's resultant displacement from 239 km=72 km
