To convert the speed of the Stegosaurus from meters per second (m/s) to kilometers per hour (km/hr), follow these steps:
1. Understand the units involved:
- We start with a speed of 1.9 meters per second (m/s).
- We need to convert this speed into kilometers per hour (km/hr).
2. Convert meters to kilometers:
- There are 1000 meters in 1 kilometer. This means each meter is [tex]\(1/1000\)[/tex] of a kilometer.
3. Convert seconds to hours:
- There are 60 seconds in a minute and 60 minutes in an hour, which means there are 3600 seconds in 1 hour.
4. Calculate the conversion factor:
- To convert from m/s to km/hr, use the ratio:
[tex]\[
\frac{3600 \text{ seconds}}{1 \text{ hour}} \times \frac{1 \text{ kilometer}}{1000 \text{ meters}} = \frac{3600}{1000} \text{ km/hr per m/s}
\][/tex]
- Simplify the ratio:
[tex]\[
\frac{3600}{1000} = 3.6 \text{ km/hr per m/s}
\][/tex]
5. Apply the conversion factor to the given speed:
- Multiply the speed in m/s by the conversion factor to get the speed in km/hr.
[tex]\[
1.9 \text{ m/s} \times 3.6 \text{ km/hr per m/s} = 6.84 \text{ km/hr}
\][/tex]
Hence, the speed of the Stegosaurus in kilometers per hour is [tex]\(6.84 \text{ km/hr}\)[/tex].
