an airplane climbs at a rate of 66.8 feet per minute. It descends at twice the rate that it climbs. Assuming it descends at a constant rate, how many feet will the aitplane descend in 30 minutes.
It descends at 133.6 feet per minute.
133.6 * 30 = ?
4008
To find out how many feet the airplane will descend in 30 minutes, we first need to determine the descent rate. Given that the airplane descends at twice the rate it climbs, we can calculate the descent rate.
Let's start by finding the climb rate. Since the airplane climbs at a rate of 66.8 feet per minute, we can express this as:
Climb rate = 66.8 feet/minute
Next, we can determine the descent rate, which is twice the climb rate:
Descent rate = 2 * Climb rate
Substituting the climb rate value in the equation, we have:
Descent rate = 2 * 66.8 feet/minute
Descent rate = 133.6 feet/minute
Now that we have the descent rate, we can calculate the total descent distance in 30 minutes by multiplying the descent rate by the time:
Total Descent Distance = Descent rate * Time
Substituting the values, we have:
Total Descent Distance = 133.6 feet/minute * 30 minutes
Total Descent Distance = 4008 feet
Therefore, the airplane will descend 4008 feet in 30 minutes.
