A submarine descends at a rate of 60 feet per minute. How long will it take to descend to a depth of 900 feet?
Answer (2)
F or m u l a f or v eo l oc i t y : v e l oc i t y = t im e d i s t an ce v = 60 min f ee t d i s t an ce = 900 f ee t v e l oc i t y ∗ t im e = d i s t an ce ∣ D i v i d e b y v e l oc i t y t im e = v e l oc i t y d i s t an ce t im e = 60 900 = 15 min u t e It will take 15 minutes.
The submarine will take 15 minutes to descend to a depth of 900 feet at a rate of 60 feet per minute. We used the formula for time, which is distance divided by velocity. This simple calculation illustrates the direct relationship between these variables.
