Thanks a lot SKULLCRUSHER5000, We're over. One of my friends said you are dating a girl named Rain, so bye.
Using the relation between velocity, distance and time, it is found that:
- The rate of the plane is of 840 km/h.
- The rate of the wind is of 210 km/h.
<h3>What is the relation between velocity, distance and time?</h3>
Velocity is <u>distance divided by time</u>, that is:

Flying against the wind, an airplane travels 2520 kilometers in 4 hours, that is:



Flying with the wind, the same plane travels 9450 kilometers in 9 hours, hence:



Hence, solving for the wind's speed:




For the plane, we have that:
v = 1050 - 210 = 840.

#SPJ1
angle C = 90°
angle O = 67°
Step-by-step explanation:
Line AC is tangent to the circle at point C. Since OC is the radius, this means that OC is perpendicular to AC. Since the sum of the interior angles of a triangle is 180°, then
23° + 90 + angle O = 180°
or
angle O = 67°
Hey there!!
Equation given :
... 78 = -2 ( m + 3 ) + m
... 78 = -2m - 6 + m
... 78 = -m - 6
... 78 + 6 = -m
... 84 = -m
... m = -84
Hope my answer helps!!
