...and finally = 0.200 south? If a bird were to start out from the origin (where the student starts) and fly directly (in a straight line) to the school, what distance would the bird cover?
db= ___ miles
 
use Pythagorus theorem, the kid travelled 0.7 (0.9-0.2) miles north and 0.4 miles west, the distance is equal to:
C^2= A^2 +B^2
C^2= 0.7^2 + 0.4^2
C^2 = 0.49+0.16
C^2 = 0.65
C = sqrt(0.65)
C= 0.81 miles
