A car is traveling at a rate of
35 meters per second. What is the car's rate in kilometers per hour? How many kilometers will the car travel in
3 hours? Do not round your answers.
35*18/5 km/h=126 km/hr
distance travel by car= speed*time=126*3=378 km
35 m/s * 1km/1000m * 3600s/hr = ? km/hr
60 * 60 * 35 = 126,000 meters per hour
Divide by 1,000 to find the kilometers per hour.
To convert the car's rate from meters per second to kilometers per hour, we need to know the conversion factor between meters and kilometers.
1 kilometer = 1000 meters
Now, let's calculate the car's rate in kilometers per hour:
First, convert from meters per second to meters per hour:
- Multiply the rate of 35 meters per second by 60 seconds to get the rate in meters per minute: 35 meters/second * 60 seconds = 2100 meters/minute
- Multiply the rate in meters per minute by 60 minutes to get the rate in meters per hour: 2100 meters/minute * 60 minutes = 126,000 meters/hour
Next, convert from meters per hour to kilometers per hour:
- Divide the rate in meters per hour by 1000 to convert to kilometers per hour: 126,000 meters/hour / 1000 = 126 kilometers/hour
So, the car's rate is 126 kilometers per hour.
To calculate how many kilometers the car will travel in 3 hours, we can use the rate of 126 kilometers per hour:
- Multiply the rate of 126 kilometers/hour by 3 hours: 126 kilometers/hour * 3 hours = 378 kilometers
Therefore, the car will travel 378 kilometers in 3 hours.
