A car on the highway travels at 90 km/hr. Express this speed in m/s. can yall show me how to convert this
Sure: Use unit conversion factors. Notice how the undesired units divide out.
Speed=90km/hr * [1000m/1km]*[1hr/3600sec]
lets do it harder: convert to miles/minute
speed=90km/hr* [1hr/60min]*[1000m/1km]*[1 mile/1609m]
The theory of this is one can multipy any measurement by one unit, and it remains intact. Examples:
1mile=5280ft: Unit conversion factors could be 5280ft/mile=1=1mile/5280
16oz=1lb: unit conversions could be 16oz/1lb=1=1lb/16oz
You use them in the form to convert to the units you need.
Speed = 90,000m/h * 1h/3600s = 25 m/s.
Sure! To convert kilometers per hour to meters per second, we need to use the following conversion factors:
1 kilometer = 1000 meters
1 hour = 3600 seconds
Now, to convert the speed from km/hr to m/s, we can follow these steps:
Step 1: Start with the given speed in km/hr, which is 90 km/hr.
Step 2: Multiply the speed by the conversion factor, 1000 meters/1 kilometer.
- This will cancel out the kilometers and give us the speed in meters per hour.
- So, 90 km/hr * 1000 meters/1 kilometer = 90,000 meters/hr.
Step 3: Divide the speed in meters per hour by the conversion factor, 3600 seconds/1 hour.
- This will cancel out the hours and give us the speed in meters per second.
- So, 90,000 meters/hr ÷ 3600 seconds/1 hour = 25 meters/second.
Therefore, the car's speed of 90 km/hr is equivalent to 25 m/s.
