The Serenity and the Mystic are sail boats. The Serenity and the Mystic start at the same point and travel away from each other in opposite directions. The Serenity travels at 14 mph and the Mystic travels at 22 mph. How far apart will they be in 3 hours?

Answer 1

To calculate the distance they will be apart in 3 hours, we need to multiply the speed of each boat by the time traveled.

The distance the Serenity will travel in 3 hours is 14 mph * 3 hours = <<14*3=42>>42 miles.
The distance the Mystic will travel in 3 hours is 22 mph * 3 hours = <<22*3=66>>66 miles.

Therefore, they will be 42 miles + 66 miles = <<42+66=108>>108 miles apart. Answer: \boxed{108}.
