it takes a submarine 30 seconds to dive 225 feet, moving at a constant speed. the captain wants to know the rate at which the submarine dives. at what rate does the submarine dive? feet per second
Answer
Explanation:
Step1: Recall the formula for speed
Speed = Distance / Time.
Step2: Substitute the given values
Here, distance (d = 225) feet and time (t=30) seconds. So, speed (v=\frac{225}{30}).
Step3: Simplify the fraction
(\frac{225\div15}{30\div15}=\frac{15}{2} = 7.5)
Answer:
(7.5)
