How long does it take to ascend 10 feet at a rate of 30 feet per minute?

To determine how long it takes to ascend 10 feet at a rate of 30 feet per minute, you can use the formula: time = distance ÷ rate.

In this case, the distance is 10 feet and the rate is 30 feet per minute. When you divide 10 feet by 30 feet per minute, you calculate the time in minutes:

10 feet ÷ 30 feet per minute = 1/3 minutes.

To convert 1/3 of a minute into seconds, multiply it by 60 seconds (since there are 60 seconds in a minute):

(1/3) × 60 seconds = 20 seconds.

This calculation confirms that ascending 10 feet at a rate of 30 feet per minute takes 20 seconds. This understanding is essential for divers to manage their ascent rates accurately to prevent issues such as decompression sickness.
