As shown in the image, we have a 30 degree angle and x, which is what we want. By doing tan30, we can find x, so tan30=x/70 and 70*tan30=x= 70*sqrt(3)/3. 120-x=height of first tower = 120-(70*sqrt(3)/3) = roughly 79.59
after 6 hours Al and Ben will be 180 miles apart.
(22 * x) + (8 * x) = 180
x = 6 hours
