The grand prix formula 1 race this weekend is in singapore. the race consists of 61 laps around a 5.067 km long track. at 225 miles per hour, how long will it take to go around once?

225 mph

 1 hr = 3600 sec

1.6 km = 1mile

1 lap = 5.067 km

 multiply all the numbers divided by conversions:

225/1 * 1/3600 * 1.6/1 * 1/5.067 =  0.0197 laps / sec 

 
1 / 0.0197 = 50.67 seconds per lap

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
