The total displacement of the hiker's movement is 10 meters, East.
Firstly, displacement is a vector quantity that has both magnitude and direction.
Displacement is an object change in position. In other words it is a change in position of an object . Displacement can also be positive, negative or even zero.
According to the question the hiker walks 15 meters due north then 10 meters east, and finally 15 meters south.
Therefore, the total change in position or total displacement is 10 meters, East.

<span>Let Ah be Annie's hour of travel in 1 day and Bh be
Brian's hour
to get Brian's hour of travel:
Ah + Bh = 20
5 (Bh +2 ) + Bh= 20
5 Bh + 10 + Bh=20
6 Bh = 20 - 10
<u>6Bh</u> = <u>10</u>
6 6</span>
Bh =1.66
To get Ah of travel 1 day
Ah = 5 (Bh + 2)
<span> = 5 (1.66 +
2) </span>
<span>
= 5 ( 3.66 )</span>
Ah = 18.30
Checking:
Ah + Bh =20
<span>
18.30 + 1.66 = 20
</span><span>19.96 = 20</span>
<span>
20 = 20</span>
(19.96 is rounded off)
