A car traveling with constant speed travels 150 in two hours. What is the speed of the car in SI UNITS?
150 what?
I MEAN 150KM IN i NEED IT IN SI UNITS
v=150km/2hrs =76km/hr and that is an SI unit, however, I suspect you mean m/s
v=76000m/1hr * 1hr/3600seconds = you do it.
Thanks I greatly appreciated it I had it mix up
To find the speed of the car in SI units, we first need to determine the formula for speed. Speed is defined as the distance traveled divided by the time taken.
In this case, the distance traveled by the car is 150 miles and the time taken is 2 hours. Therefore, we can use the formula
Speed = Distance / Time
Substituting the given values, we get
Speed = 150 miles / 2 hours
To convert miles to the SI unit of length, which is meters, we need to know the conversion factor. The commonly used conversion factor between miles and meters is 1 mile = 1609.34 meters.
So, we can convert the distance from miles to meters:
Distance (in meters) = 150 miles * 1609.34 meters/mile
Now we can substitute the values and calculate the speed:
Speed = (150 miles * 1609.34 meters/mile) / 2 hours
Canceling the unit of miles, we are left with meters/hour. To convert this to meters/second, we need to remember that there are 3600 seconds in an hour. So, we divide the speed by 3600:
Speed = [(150 miles * 1609.34 meters/mile) / 2 hours] / 3600 seconds/hour
Evaluating this expression will give us the speed of the car in meters per second, which is the SI unit of speed.
