A primatologist recorded vocalizations from a troop of 8 monkeys. Each monkey emitted either a low, medium, or high-pitched call. On a given day, 3 monkeys used high-pitched calls (each making 6 calls), 4 used medium (each making 9 calls), and the remaining used low (each making 5 calls). If each call lasts 1.2 seconds, what was the total duration of all calls in minutes?

Primatologist Captures Vocal Records: How Long Did the Monkey Troop Open Up? A groundbreaking study by a leading primatologist has shed light on the complex vocal communication of a wild monkey troop, revealing fascinating details about their daily vocal activity. In a documented observation of 8 monkeys, researchers recorded distinct call frequencies across three distinct pitch levels—low, medium, and high—offering new insight into primate social dynamics. The troop’s vocal output varied clearly by call pitch, with each monkey producing calls of either low, medium, or high pitch. According to the research team, 3 monkeys emitted high-pitched calls, each producing exactly 6 calls. 4 monkeys used medium-pitched calls, each making 9 calls, while the remaining 1 monkey—among the 8—recognized for low-pitched vocalizations, each emitting 5 calls. Now, putting the numbers into motion:
- High-pitched calls:
3 monkeys × 6 calls = 18 calls
- Medium-pitched calls:
4 monkeys × 9 calls = 36 calls
- Low-pitched calls:
1 monkey × 5 calls = 5 calls
