Remark
the question depends on d= r * t
d = the distance in miles.
r = the rate of travel in miles per hour
t = the time in hours.
Step One
Rearrange the formula so you are solving for the rate.
d = r * t Divide by t
4 5/6 = (4*6 + 5)/6 = 29/6
r = d / t
Step Two
Substitute into the equation.
Step Three
Turn the bottom fraction upside down. Multiply these two together.
r =
r = 29/4 miles hour.
Step Four
Solve for d when t = 1 hour.
d = ??
r = 29/4 miles / hour
t = 1 hour.
d = 29/4 * 1
d = 29/4 miles
That's as simple as you can get it unless you want 7 1/4 miles or 7.25 miles
First, let's calculate the horizontal and vertical components of the wind speed (W) and the airplane speed (A), knowing that south is a bearing of 270° and northeast is a bearing of 45°:
Now, let's add the components of the same direction:
To find the resultant bearing (theta), we can use the formula below:
The angle -86° is equivalent to -86 + 360 = 274°.
Therefore the correct option is b.
