Question

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 21 mph. How far apart will they be in 3 hours?

Answer 1

Step-by-step explanation:d = 14t + 21t = 35t

So, after 3 hours, the distance between the boats will be:

d = 35 * 3 = 105 miles

Therefore, the Serenity and the Mystic will be 105 miles apart after traveling for 3 hours.

Answer 2

Let d be the distance between the two boats after they have been traveling for t hours.

Since the Serenity and the Mystic are traveling in opposite directions, the total distance they cover in t hours is equal to the sum of their individual speeds times t:

d = 14t + 21t = 35t

So, after 3 hours, the distance between the boats will be:

d = 35 * 3 = 105 miles

Therefore, the Serenity and the Mystic will be 105 miles apart after traveling for 3 hours.
