TWO PLANES WHICH APART, FLY TOWARDS EACH OTHER. THEIR SPEEDS DIFFER BY 60 MILES PER HOUR. THEY PASS EACH OTHER AFTER 5 HOURS. FIND THEIR SPEEDS.

approach speed = v + v+60 = 2 v+60
d = rate * time = (2v+60)(5) = 10 v + 300
unfortunately we were not given d, their distance apart so I am faced with a problem or a typo.
