# An airplane flies an altitude of 38,000 feet. As it nears the airport, the plane begins to descent at a rate of 600 feet per minute. At this rate, how many minutes will the plane take to descent to 18,800 feet?

32 minutes

#### Explanation:

Altitude descended $38000 - 18800 = 19200$ft

Descent rate (vertical speed) = 600ft/min

$\text{speed" = "distance"/"time}$

so $\text{time" = "distance"/"speed}$

$t = \frac{19200}{600} = 32$
