“……Atkinson’s time has since been beaten by Matt LeBlanc, who completed the same lap in the same car a tenth of a second faster.” http://en.wikipedia.org/wiki/Rowan_Atkinson

What does “a tenth of a second ” mean in that sentence above?

Thanks!

Thanks everyone! Does it mean 1/10 second or 10/60 second?

• Imagine splitting a second into 10 pieces.

That’s a really short time.

So basically it’s much shorter than a millisecond.

• It’s a measurement of time. Same as dividing a meter into centimeters or millimeters or an inch into 1/8 or 1/16. It’s just taking a larger unit and breaking it into smaller ones. So a tenth of a second is well, .1 of a full second.

And also, a millisecond is 1/1000 of a second, so it is 100 times shorter than a tenth of a second.

• There a 100 milliseconds in 1 second. One tenth of a second is 10 milliseconds

• It means he beat him by 0:00:10 seconds faster which is less than a second. It is a tenth of a second.

• One-tenth of a second is called a “decisecond” (not to be confused with ten seconds which is called a “decasecond”) However, in common parlance, simply saying “tenth of a second” is considered quite acceptable for nearly all applications.
