Question

A skydiver falls at a rate of t = 0.75 √ x seconds to freefall x feet. How long, in seconds, does it take the skydiver to freefall 1200 feet? A. 9 √ 3 B. 15 √ 3 C. 3 √ 3 D. 20 √ 3

Answer 1

The skydiver takes 15 √3 seconds to freefall 1200 feet.

Step-by-step explanation:

To find the time it takes for the skydiver to freefall 1200 feet, we can use the given formula t = 0.75 √x. Plugging in the value of x = 1200 into the formula, we get t = 0.75 √1200.

First, we can simplify √1200 as 20√3. Then, multiplying 0.75 by 20√3, we find that the skydiver takes 15 √3 seconds to freefall 1200 feet.

Therefore, the correct answer is B. 15 √3 seconds.
