Solve the problem.

Three trains — one eastbound, one westbound, and one northbound — leave a city at the same time. The speed of the northbound train is 30 miles per hour greater than the speed of the eastbound train. After 5 hours, the distance between the westbound train and the eastbound train is 450 miles. Twice the speed of the westbound train is 60 miles per hour more than the speed of the northbound train.  Find the speeds of the three trains.

▸ eastbound, 40 mph; westbound, 60 mph; northbound, 70 mph

▸ eastbound, 20 mph; westbound, 70 mph; northbound, 60 mph

▸ eastbound, 60 mph; westbound, 60 mph; northbound, 30 mph

▸ eastbound, 30 mph; westbound, 60 mph; northbound, 60 mph
