A submarine can descend at a rate of -2.5 meters/second. Suppose that the submarine begins at a depth of -25 meters.

1 answer:

5 0

The distance from the initial depth to the maximum depth is:
abs (-200- (-25))= 175 m (distance is always >=0, so we have to take the abs).

175 m* (1 sec/ 2.5m)= 70 sec.

It would take the submarine 70 seconds to reach its maximum depth.

Hope this helps~

A pencil factory makes 50 cases of pencils in 5 hours.

Oduvanchick [21]

If a pencil factory makes 50 cases of pencils in 5 hours. Let's first find out how many cases are made per hour.

50 ÷ 5 = 10 cases per hour

Now you need to know how long it will take to make 55 cases. Since we already know that it takes 5 hours to make 50 cases. So you need to know how many cases for the extra 5 cases. If it takes 1 hour to make 10 cases, it would only take 1/2 hour to make 5 cases.

So it would take 5 1/2 hours to make 55 cases.

Hope this helps. :)
