Answer:
Step-by-step explanation:
Given
varies directly with 
This means
∝
This can be written as:
where 
is the constant of proportionality.
We know that when 
then 
. Using this we can find value of .
so, we have
Dividing both sides by 8 to isolate .
∴ 
when 
then will be
∴

Answer:
48
Step-by-step explanation:
think of the a squared plus b squared equals c squared. plug in the 36 in either b or a. then plug in the 60 in c's spot. solve and get 48. you can check the answer by solving 48 squared plus 36 squared equals 60 squared. both sides are equal and both come out to be the 3600
Given :
A submarine started at the surface of the water and was moving at -15 meters per minute.
The submarine traveled at this rate for 48 minutes before coming to rest on the ocean floor.
To Find :
The change in the submarine position.
Solution :
We need to find the position of submarine position from the surface of water.
Distance travelled = Speed × Time
Distance travelled = -15 m/min × 48 min
Distance travelled = 720 m
Therefore, the position of submarine is 720 m below the surface of ocean.
