How fast is 11 meters per a second in kilometers per hour?

Step 1. Speed=distance/time=11 meters/sec

Step 2. Conversions: 1000 m = 1 km and 1 hour = 60 minutes = 60 minutes * 60 seconds/ minute= 3600 seconds.

Step 3. Do conversions to get kilometers/hour: (11 meters/sec)(1 kilometers /1000 meters)(3600 seconds / 1 hour). Notice the units meters and seconds will cancel to get our desired units of kilometers per hour.

Step 4. Then, 11*(1/1000)*(3600)=39.6 kilometers per hour.

Step 5. ANSWER: 39.6 km/hr.

I hope the above steps were helpful.
