Answer:
10 hours
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:
![\text{Time }=\dfrac{\text{Distance Traveled}}{\text{Speed}}](https://tex.z-dn.net/?f=%5Ctext%7BTime%20%7D%3D%5Cdfrac%7B%5Ctext%7BDistance%20Traveled%7D%7D%7B%5Ctext%7BSpeed%7D%7D)
![\text{Time }= \dfrac{300}{30} = \bold{10\ hours}](https://tex.z-dn.net/?f=%5Ctext%7BTime%20%7D%3D%20%5Cdfrac%7B300%7D%7B30%7D%20%3D%20%5Cbold%7B10%5C%20hours%7D)
So, the answer is <em>10 hours</em>.

Answer:
4m is the answer.
Step-by-step explanation:
a = 3m
b = ?
c = 5m
According to the Pythagoras theorem,
a² + b² = c²
3² + b² = 5²
9 + b² = 25
b² = 25 - 9
b² = 16
b = 4m
∴ The distance between the ladder and the bottom of the slide is 4m.
