Martin came in first place in the 10 meter dash with a time of 14 7/10 seconds. Samuel came in second place with a time of 15 23/100 seconds. By how many hundredths of a second did Martin beat Samuel?
15.23 - 14.7 = ?
To find out by how many hundredths of a second Martin beat Samuel, we need to subtract Samuel's time from Martin's time.
Martin's time is 14 7/10 seconds, which can be written as 14.7 seconds. Samuel's time is 15 23/100 seconds, which can be written as 15.23 seconds.
To subtract these two times, align the decimal points:
14.70
- 15.23
________
-0.53
Therefore, Martin beat Samuel by -0.53 seconds.
Since the question asks for the answer in terms of hundredths of a second, we need to multiply -0.53 by 100 to convert it to hundredths:
-0.53 * 100 = -53
Therefore, Martin beat Samuel by 53 hundredths of a second.
