2. geez - impatient much? repost after 4 minutes, and don't even fix you error?

distance clearly equals 4+3

displacement is impossible to say, because we don't know the direction from a to b. It could be anything from 1 to 7

3. Given: AB = 4km[0o],
BC = 3km[90o], (should be 90o between BC and AB),

d = 4 + 3 = 7km.

Disp. = sqrt(4^2+3^2) =

4. Total distance = 4 km + 3 km = 7 km
Displacement = the area of a triangle as the figure is making a right angle triangle so
1/2 . B. H
1/2. 3 km . 4 km
= 6 km
