koto traveled 5,000 meters north from her house with an average velocity of 4.5 m/s. what was the time of her trip? (there are 60 seconds in 1 minute.) 18.5 minutes 20.4 minutes 2 hours 3 hours
Answer
Explanation:
Step1: Recall velocity - time - distance formula
We know that $v=\frac{d}{t}$, where $v$ is velocity, $d$ is distance and $t$ is time. Rearranging for $t$, we get $t = \frac{d}{v}$.
Step2: Substitute given values
Given $d = 5000$ m and $v=4.5$ m/s. So $t=\frac{5000}{4.5}\text{ s}\approx1111.11\text{ s}$.
Step3: Convert seconds to minutes
Since 1 minute = 60 seconds, then $t=\frac{1111.11}{60}\text{ minutes}\approx18.5$ minutes.
Answer:
18.5 minutes
