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
