During the holiday, Wang Qiang and his classmates traveled to an island. They landed at point A according to the route shown and rented a bicycle, which went 8 kilometers east.
Establish a plane rectangular coordinate system with the east as the positive semi-axis of X axis, the north as the positive semi-axis of Y axis, and the landing point as the coordinate origin.
Their movements in the X-axis direction are 8 units to the right, 3 units to the left and 1 unit to the right.
The movement in the Y-axis direction is 2 units up and 6 units up.
Therefore, the coordinate of the scenic spot B is (6,8).
Connect AB, make a vertical line of X axis from B, and intersect X axis at C.
In the right triangle ABC, AC=6 and BC=8.
So AB= 10
AB straight line distance 10 km.
