Long Answer Question : A submarine descended 3/5 of a kilometer in 1/5 of an hour. What was the Submarine's rate of Descent in Kilometers per hour ? Plz show work and explain:)

Answer 1

The Submarine's rate of Descent is
`3(km)/(h)`

Explanation:

we know that

To find the Submarine's rate of Descent apply proportions

so

`((3/5))/((1/5))(km)/(h)=(x)/(1)(km)/(h) \\ \\x=(3/5)/(1/5)\\ \\x=3(km)/(h)`
