Given that:
Equation to represent the relation between distance, in miles and time
in seconds:
<em>A. </em>
To find: The speed of airplane in miles per second.
Formula for speed is given as:
Here, we will have to find the value of .
Dividing the given equation by , we get:
is in miles and
is in seconds.
Therefore, the answer is <em>0.15</em>.
<em>B.</em>
Distance traveled in 30 seconds.
Given that: = 30 seconds
To find: in miles
<em>C.</em>
The time taken to travel a distance of 12.75 miles.
Given that :
To find: seconds
From right triangle trigonometry, we have the following:
,
where the "opposite side" means the opposite side to angle with measure
, and "adjacent side" means the adjacent side to angle with measure .
is a constant which can be found using a calculator.
In the calculator of the pc press: view - scientific - 35 - tan.
This gives
Thus, back in the equation we substitute as follows and solve:
Answer: 8.4 cm
where the "opposite side" means the opposite side to angle with measure
In the calculator of the pc press: view - scientific - 35 - tan.
This gives
Thus, back in the equation
Answer: 8.4 cm
