A race car has a top speed of 330 km/hr. What speed is that in miles/sec?
What a strange unit to convert to .
1 km = 0.621371 miles
1 hr = 3600 seconds
330 km/h = (0.621371)(330)miles / 3600 sec
= appr .057 miles/second
To convert kilometers per hour (km/hr) to miles per second (mi/sec), we need to follow these steps:
Step 1: Convert kilometers per hour to miles per hour
1 kilometer is equal to 0.621371 miles.
So, to convert kilometers per hour to miles per hour, we multiply by 0.621371.
330 km/hr * 0.621371 = 205.051 miles/hr
Step 2: Convert miles per hour to miles per second
1 hour is equal to 3600 seconds.
To convert miles per hour to miles per second, we divide by 3600.
205.051 miles/hr / 3600 = 0.056958 miles/sec
Therefore, the top speed of the race car, 330 km/hr, is approximately 0.056958 miles/sec.
