Hi everyone,
In one of the questions of the Official Guide, I noticed the following:
... Cindy drove her car 290 miles, rounded to the nearest 10 miles ...
According to me, this means she has driven between 285 en 294 miles. In the book, I quote: "Since the miles are rounded to the nearest 10 miles, they can range anywhere from 284 miles to 295 miles."
Rounding 284 to the nearest 10 miles is 280, rounding 295 makes 300 ?!
In the same question, same issue:
... Cindy used 12 gallons of gasoline, rounded to the nearest gallon ...
I quote from the answer: "Since the gallons are rounded to the nearest gallon, they can range anywhere from 11.4 gallons to 12.5 gallons."
Are rounding rules different in the US than they are in Europe?
