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?
To find the distance between the two sailboats after 3 hours, we need to calculate the total distance each boat will travel separately.
First, let's calculate the distance traveled by the Serenity after 3 hours. The Serenity travels at a speed of 14 mph, so we can use the formula distance = speed × time. Therefore, the distance travelled by the Serenity is 14 mph × 3 hours = 42 miles.
Next, let's calculate the distance traveled by the Mystic after 3 hours. The Mystic travels at a speed of 22 mph. Using the same formula, the distance travelled by the Mystic is 22 mph × 3 hours = 66 miles.
Since the two sailboats are traveling in opposite directions, we can add their distances together to find the total distance between them after 3 hours. 42 miles + 66 miles = 108 miles.
Therefore, after 3 hours, the Serenity and the Mystic will be 108 miles apart.
To find out how far apart the Serenity and the Mystic will be in 3 hours, we can calculate the total distance traveled by each boat.
The distance traveled by the Serenity in 3 hours is calculated by multiplying its speed (14 mph) by the time (3 hours): 14 mph * 3 hours = 42 miles.
Similarly, the distance traveled by the Mystic in 3 hours is calculated by multiplying its speed (22 mph) by the time (3 hours): 22 mph * 3 hours = 66 miles.
Since the boats are traveling in opposite directions, we need to add their distances traveled to find the total distance between them. The total distance will be: 42 miles + 66 miles = 108 miles.
Therefore, after 3 hours, the Serenity and the Mystic will be 108 miles apart.
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}.
