My name is luke

My question is, i race four wheelers on weekends and was trying to find out how fast we are going i race 500 ft.in about 6.00 seconds .how do you figure out the speed i am traveling?

 

Hi Luke,

Speed is in the units of distance divided by time. You gave us a distance measured in feet and a time in seconds so your speed in feet per second is

 500/6  = 83.3 feet per second.

I expect however that you want the speed in miles per hour. There are 5280 feet in a mile so

500 ft = 500/5280 miles.

There are 60 seconds in a minute and 60 minutes in an hour and hence there are 60 x 60= 3600 seconds in an hour. Thus your time of is

6 seconds = 6/3600  hours

To find your speed in miles per hour divide the number of miles by the number of hours.
