How to
ask for help Distance from the observation point to the last point
= start to end - the beginning of a landmark
1. distance from beginning to end

. How doProblems asking for the distance from the point to the final point
= start to the last - start to the point! 1. Find the distances from the beginning to the end
S =? A = 3
U = 0 T = -



V2 24 V = = U2 2As
242 = 02 2 (3) (s)
576 = 0 6S
s. = 96 m

2.Find the distances from the beginning to the point S
=? A = 3
U = 0 T = -
V = 12

V2 = U2 2As
122 = 02 2 (3) (s)
144 = 0 6S
s. = 24 m

so far from the observation point = 96 - 24 = 72 m
