A car leaves New Orleans traveling 50 miles per hour. An hour later a second car leaves New Orleans following the first car, traveling 70 miles per hour. How many hours after leaving New Orleans will it take the second car to overtake the first?

Car I 50 mph.
Car II 70 mph
Let second car meet the CAr I after time t
Distance traveled by both is same when they meet
Distance traveled by Car I = 50 (t+1) [because it starts 1 hour early]
distance traveled by car II = 70 t
70t=50(t+1)
70t=50t+50
20t=50
/20
t=2.5
Car II meets Car I after 2.5 hours
