Answer:
48 minutes
Step-by-step explanation:
Given: The distance between A and B is 8 miles. Speed of one jogger is 4 miles per hour, and speed of other jogger is 6 miles per hour.
To find: After how many minutes will the joggers meet, if they are running towards each other.
Solution:
Let both the joggers will meet after t hours, at point P between A and B.
We know that 
Let the jogger running at a speed of 4 miles per hour starts from point A.
So,
Let the jogger running at a speed of 6 miles per hour starts from point B.
So,
We have,
So, both the joggers will meet after 0.8 hours or 
minutes.
Hence, the joggers will meet after 48 minutes.

Answer:
x = 8√5
Step-by-step explanation:
In the figure attached, there are three right angle triangles.
So, by Pythagoras theorem,
y²+ 4² = z²
y² + 16 = z²------(1)
Similarly x² = 16² + y²--------(2)
and (16 + 4)² = x² + z²
20² = x² + z²-------(3)
Now we put the value of z² from equation 1 to equation 3
20² = x² + y² + 16
x² + y² = 400 - 16
x² + y² = 384
y² = 384 - x²------(4)
Now we put the value of y² from equation 4 to equation 2
x² = 16² + 384 - x²
2x² = 256 + 384
2x² = 640
x² = 320
x = 8√5
Therefore x = 8√5 will be the answer.
