Well you equal out the two angles to each other and solve for x. then you just plug the the number you got for x back into the equations to get your answers
Basiclaly, when will total distance equal distance they are apart
distance apart=280
distance=speed times time
assuming they travel sasme amount of time
time=t
distance=speed times time
d1=95 times t
d2=105 times t
total distance=d1+d2
280=d1+d2
280=95t+105t
280=200t
divide both sides by 200
1.4=t
answer is 1.4 hours or 84 mins
