Step-by-step explanation:
Given:
Average speed of submarine = 10 mph
Speed of carrier in the opposite direction = 20 mph
Distance between the submarine and carrier = 300 mi
To find:
The time taken so that the distance between them is 300 mi ?
Solution:
The relative speed when they are traveling in opposite direction = 10+20 = 30 mph
Formula:
So, the answer is <em>10 hours</em>.
For the left-hand triangle we know: 
.
Solving for
we have:
So the angles on the left are: 47,31 and 102 degrees.
On the right we have
Substituting known values and solving we get:
[tex]y=72\°[/tex}
So the angles on the right are, 72, 61 and 47 degrees.
Solving for
So the angles on the left are: 47,31 and 102 degrees.
On the right we have
