distance = 12+4+1=17 km
displacement = 11.704 km
answer is coming from the pythagoras theorem

Distance = 12km + 4km + 1km = 17 km
If the unit vectors along north and east is j and i respectively then
Displacement = (12(-j) + 4(-i) + j) km
= (-4i + 11j) km
Magnitude of displacement = sqrt(4^2 + 11^2) = 11.70 km
If the unit vectors along north and east is j and i respectively then
Displacement = (12(-j) + 4(-i) + j) km
= (-4i + 11j) km
Magnitude of displacement = sqrt(4^2 + 11^2) = 11.70 km
