The rate of the plane in still air is 870km/h and the rate of the wind 210km/h.
<h3>What is speed?</h3>
Speed has the dimensions of distance divided by time.
Let Speed of airplane be x km/h and Speed of Wind be y km/h
Speed direction of wind (x+y)
Speed in opposition of wind (x-y)
Now, using speed x time= distance
7( x-y)=4620
(x-y)=4620/7
=660------------------(1)
Similarly,
8(x+y)=8640
(x+y) =8640/8=1080-----------------------(2)
Adding (1) and (2)
2x=1740
x=870 km/h
Subtracting (1) from (2)
2y=420
=>y=210 km/h
So rate of airplane =870km/h
rate of wind=210km/h

Answer:
is the answer
Step-by-step explanation:
just add the 3 and -5 and u get -2
if the main number is the same keep it
ik this doesnt make any sense but hope this helps....
ANSWER
Option D is correct
EXPLANATION
We resolve the forces into component forms.
Also the second is resolved to obtain,
To find the resultant vector, V, We add the corresponding components of the two forces to get:
The correct answer is D.
Answer:
127 degrees
Step-by-step explanation:
540 degrees is what the interior of a pentagon should add up to. So you do 540-156-72-98-87=127. The measure of the final interior angle is 127 degrees.
