Answer:
c
Step-by-step explanation:
1/2x2/5=2/10
multiply both denominators by each other, then with numerator.
What's the question she got the answer wrong to?
The wind is blowing at the rate of 4 miles per hour
<h3>Speed and distances</h3>
The formula for calculating speed is expressed as:
Speed = Distance/Time
Given the following parameters
Speed of airplane = 18 miles per hour
Speed in wind = 2.2 * 10 = 22 miles/hr
Speed of the wind = 22 - 18
Speed of the wind = 4mi/hr
Hence the wind is blowing at the rate of 4 miles per hour

so if you do 1/tan(10) in the calculator you get 5.67128
round the answer as needed
