Since the cars are moving in opposite direction then their resultant speed = (60+50) mph = 110 mph Time = Distance/ speed Distance = 220 miles speed = 110 mph so time=distance/speed = 220/110 = 2 hours.

Suppose the time taken is 't' hours. Then distance traveled by first car = speed*time = 60t miles distance travelled by second car = 50t miles Separation between them = 60t + 50t = 110t (separation is added because they are moving away from each other) For separation to become 220 miles 110t = 220 => t = 2 hours
