Answer:
the Velocity of the plane is 100 mi/hr along the northeast direction
Step-by-step explanation:
According to the Question,
- Given That, the Initial velocity of the plane is 150 mi/hr along the east north direction and the wind is blowing at 50 mi/hr along the southwest direction
since the velocity of wind and plane is exactly opposite
- the relative velocity of the plane with respect to the wind is given by
, where 
is the velocity of plane = 150mi/hr and 
= velocity of wind = 50 mi/hr
- Therefore, Relative Velocity = 150-50 ⇒ 100mi/hr along northeast direction
Thus, the velocity of the plane is 100 mi/hr along the northeast direction
Solving this problem is just pretty straight forward. All
we have to do is to use the concept of ratio and proportion.
First, let us say that the change in elevation in half an
hour (30 minutes) takes the value of variable x.
From the given, we know that the ratio of height and time
is:
152 m : 8 minutes
And the next ratio is:
x : 30 minutes
To solve for the value of x, we equate the two:
152 m : 8 minutes = x : 30 minutes
We know that the symbol of ratio which is “:” also means
division, therefore:
152 m / 8 minutes = x / 30 minutes
x = 152 m * 30 minutes / 8 minutes
x = 570 m
Therefore the change in elevation after half an hour is
570 meters.
Answer:
$19.49
Step-by-step explanation:
48.2 - 29.6 = 18.6
18.6 + 0.89 = 19.49
