A submarine travels 315 feet straight down for 90 seconds. What is the average speed in feet per second of the submarine?
To find the average speed in feet per second of the submarine, we need to divide the total distance traveled by the total time taken. In this case, the total distance traveled by the submarine is 315 feet, and the total time taken is 90 seconds.
So, to find the average speed, we can use the formula:
Average Speed = Total Distance / Total Time
Plugging in the values, we have:
Average Speed = 315 feet / 90 seconds
Now, we can divide 315 feet by 90 seconds to get the average speed in feet per second.
Average Speed = 3.5 feet per second
Therefore, the average speed of the submarine is 3.5 feet per second.
