a submarine moved south at a constant velocity for 3.5 hours. it moved 98 kilometers in that time. what was the submarines velocity? write your answer as a whole number. kilometers per hour to the south
Answer
Explanation:
Step1: Recall velocity formula
Velocity $v=\frac{d}{t}$, where $d$ is distance and $t$ is time.
Step2: Substitute values
Given $d = 98$ kilometers and $t=3.5$ hours, so $v=\frac{98}{3.5}$.
Step3: Calculate result
$v = 28$ kilometers per hour.
Answer:
28
