Robert found an old record player at a garage sale. He bought it for $8.25 and was given eight long playing records for free. Robert presented his garage sale find to his father with a flourish. His father was delighted with the player. He said the old albums played at 33 1/3 revolutions per minute. How many revolutions would a record make in 15 minutes?
15 * 33 1/3 = ?
is it 500 revolutions
Yes.
thanks, you are great :)
You're welcome. :-)
To find out how many revolutions a record would make in 15 minutes, we need to determine the number of complete revolutions the record makes in one minute, and then multiply that by 15.
Given that the old albums played at 33 1/3 revolutions per minute, we can convert this into a decimal by multiplying the whole number (33) by the denominator (3) and adding the numerator (1). So, 33 1/3 can be written as 33 + (1/3) = 33.33 (rounded to two decimal places).
Now, we can multiply 33.33 (the number of revolutions per minute) by 15 (the number of minutes) to find the total number of revolutions the record would make in 15 minutes.
33.33 revolutions/minute * 15 minutes = 499.95 revolutions
Therefore, a record would make approximately 499.95 revolutions in 15 minutes. Since we can't have a fractional number of revolutions, we can round this down to the nearest whole number.
Hence, a record would make approximately 499 revolutions in 15 minutes.
