Two cyclicst leaves from the same location with an ange of 63 degrees between their paths. Johal cycles at a speed of 35 km/h and Julio at a speed of 40 km/h. How far apart are they after 3 hrs?
After 3 hrs.....Johal has traveled 3 * 35 = 105 km
And Julio has traveled 3 * 40 = 120 km
We can use the Law of Cosines to find the distance^2, d^2, between them
d^2 = 105^2 + 120^2 -2(105 * 120) cos (63°)
d^2 = 13984
d = sqrt ( 13984) ≈ 118.25 km
