A boat which travels 100 km (N), then 40 km (N), and finally 80 km (S). The entire trip takes 6.5 hours.
A.) Calculate the total displacement of the boat
B.) calculate the velocity of the boat

Total displacement =100km(N)+40Km(N)80Km(S)=60Km
time in seconds=6.5hrs*(60min/1hr)*(60 sec/1min)=
Velocity=displaceent/time=60 x10^3 m/2.34 x10^4 s

how isn't the displacement 220km ? d2d1, 80140 ?
