LectureNotes said it is good to commit yourself for a person crosses a 600 m long street in 5 minutes. What is his speed in km per hour?
Answer: To find the speed of a person who crosses a 600-meter long street in 5 minutes in kilometers per hour (km/h), follow these steps:
- Convert the distance from meters to kilometers:
- Since 1 kilometer (km) is equal to 1000 meters (m), we convert 600 meters to kilometers.
\text{Distance in km} = \frac{600 \text{ m}}{1000} = 0.6 \text{ km}
- Convert the time from minutes to hours:
- Since 1 hour is equal to 60 minutes, we convert 5 minutes to hours.
\text{Time in hours} = \frac{5 \text{ minutes}}{60} = \frac{1}{12} \text{ hours}
- Calculate the speed in km/h:
- Speed is calculated by dividing the distance by the time.
\text{Speed} = \frac{\text{Distance}}{\text{Time}} = \frac{0.6 \text{ km}}{\frac{1}{12} \text{ hours}} = 0.6 \text{ km} \times 12 = 7.2 \text{ km/h}
Therefore, the speed of the person is 7.2 kilometers per hour (km/h).
