A rescue boat just picked up some sailors in a lifeboat. Now the rescue boat is heading north at 15 miles per hour. The lifeboat, which they abandoned, is drifting south at a speed of 5
miles per hour. How long will it be before the rescued sailors are 15 miles from their lifeboat?

if they at 5 miles right now it should take 10 more miles to reach their target/ location
