Asubmarine descended 3/5 of a kilometer in 1/5 of an hour. what was the submarine’s rate of descent in kilometers per hour?

3 kilometer per hour

Step-by-step explanation:

We are given that a submarine descended 3/5 of a kilometer in 1/5 of an hour and we are to find the submarine's rate of descent in kilometers per hour.

Using the ratio method to find the rate of descent:

Therefore, the rate of descent of submarine is 3 kilometer per hour.

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
