Two paths diverge at a 48 degree angle. Two mountain bike riders take separate routes at 8km/hr and 12km/hr. How far apart are they after 2 hours? Include a diagram.

Answer 1

Is elevation constant?

distance=velocty*time

you do not have time.
Figure the distance for each. You have on the triangle SAS
you can use the law of consines to figure the last side.

distance^2=d2^2+d1^2 -2*d2*d1*cos48
