A dolphin takes a breath typically 6 times in 30 minutes. Predict how times a dolphin breaths in 2 hours and 45 minutes
Using the ratio of breaths to time (6 breaths in 30 minutes), we can calculate the number of breaths a dolphin takes in 2 hours and 45 minutes.
First, convert 2 hours and 45 minutes to minutes:
2 hours = 2 * 60 = 120 minutes
Total time = 120 minutes + 45 minutes = 165 minutes
Now, calculate how many sets of 30 minutes are in 165 minutes:
165 minutes / 30 minutes = 5.5 sets
Since a dolphin takes 6 breaths in 30 minutes, we can calculate the total number of breaths in 165 minutes:
5.5 sets * 6 breaths = 33 breaths
Therefore, a dolphin is predicted to take 33 breaths in 2 hours and 45 minutes.
