Answer:
When a physical change in a sample occurs, composition of the sample does not change. It stays the same. It stays the same. Also, the properties of the sample will still be the same
The answer to your question 25.333333333
Actual displacement that he required to move
towards North
Displacement that he moved due to snow is
at 47 degree North of East
now in vector component form we can say



now the displacement that is more required to reach the destination is given as



so the magnitude of the displacement is given as


its direction is given as

so it is 5.54 km towards 5.38 degree North of West.
