Shalnov [3]

Answer:

170°

Step-by-step explanation:

To convert from radians to degrees

degree measure = radian measure × $\frac{180}{\pi }$ , thus

degree = $\frac{17\pi }{18}$ × $\frac{180}{\pi }$

Cancel π on numerator/denominator and 18/ 180 by 18

degree measure = = 17 × 10 = 170°

To avoid a storm, a passenger-jet pilot descended 0.38 mile in 0.4 minute. What was the plane's average change of altitude per m

Alenkinab [10]

Answer:

0.55 mile / minute

Step-by-step explanation:

The average change of altitude per minute would simply be the ratio of distance descended over time. That is:

average change of altitude = distance / time

average change of altitude = 0.44 mile / 0.8 minutes

average change of altitude = 0.55 mile / minute
