One car drives north at 60 mph. Another car leaces 30 minutes later and drives south at 50 mph. How long will it take for the two cars to be 360 miles apart?

After the second car starts out,

D = 30 + 110 H

360 = 30 + 110 H

330 = 110 H

H = 330/110

H = 3 hours after the second car leaves.

That's 3.5 hours after the first car leaves.
