Question

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

Explanation:

Step1: Recall the formula for time

The formula that relates distance ($d$), velocity ($v$), and time ($t$) is $t=\frac{d}{v}$. Here, the distance $d = 5000$ meters and the velocity $v=4.5$ m/s.

Step2: Calculate time in seconds

Substitute the values into the formula: $t=\frac{5000}{4.5}\approx1111.11$ seconds.

Step3: Convert seconds to minutes

Since there are 60 seconds in 1 minute, we divide the time in seconds by 60: $\frac{1111.11}{60}\approx18.5$ minutes.

Answer:

18.5 minutes
