A student bikes to school by traveling first d_N = 0.900\rm {miles} north, then d_W = 0.600\rm {miles} west, and finally d_S = 0.100\rm {miles} 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 d_b would the bird cover?

north .9 - .1 = .8

west .6

right triangle beacuse north is perpendicular to west

c^2 = a^2 + b^2

c^2 = .8^2 + .6^2

3,4 ,5 triangle = 2 (.3 , .4 , .5)

so answer is 1

or do it out

.8^2 = .64

.6^2 = .36

sum is 1

sqrt (1) = 1
