Koto traveled 5,000 meters north from her house with an average velocity of 4.5m/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

To find the time of Koto's trip, we can use the formula for velocity:<br /><br />\[ \text{Velocity} = \frac{\text{Distance}}{\text{Time}} \]<br /><br />Rearranging this formula to solve for time gives us:<br /><br />\[ \text{Time} = \frac{\text{Distance}}{\text{Velocity}} \]<br /><br />Given that the distance is 5,000 meters and the average velocity is \(4.5 \, \text{m/s}\), we can substitute these values into the formula:<br /><br />\[ \text{Time} = \frac{5000 \, \text{meters}}{4.5 \, \text{m/s}} \]<br /><br />Calculating this gives:<br /><br />\[ \text{Time} = \frac{5000}{4.5} \approx 1111.11 \, \text{seconds} \]<br /><br />Now, convert seconds into minutes by dividing by 60 (since there are 60 seconds in a minute):<br /><br />\[ \text{Time in minutes} = \frac{1111.11}{60} \approx 18.52 \, \text{minutes} \]<br /><br />Rounding to one decimal place, the time of her trip is approximately 18.5 minutes.<br /><br />Therefore, the correct answer is:<br /><br />18.5 minutes
