If a plane climbs at a rate of 800 feet per minute, how long will it take to climb 16,000 feet?

To determine how long it will take a plane to climb 16,000 feet at a rate of 800 feet per minute, you can use the formula for time, which is derived from the relationship between distance, rate, and time. The formula is:

Time = Distance ÷ Rate.

Plugging the values into this formula, you have:

Time = 16,000 feet ÷ 800 feet per minute.

When you perform this division, it simplifies to:

Time = 20 minutes.

This means that to climb 16,000 feet at a consistent rate of 800 feet per minute, the plane would take 20 minutes to reach its altitude.

The option indicating a climb time of 22 minutes suggests a misunderstanding of either the rate of ascent or the distance to be climbed, while the other choices do not satisfy the mathematical calculation derived from the given data. Thus, the correct choice is the one that accurately reflects the calculated time of 20 minutes.
