Lola needs to sign 96 invitations. Using a stopwatch that measures time to tenths of a second, it takes Lola 5.3 seconds to sign her full name. Going by the accuracy of the stopwatch, which is the most accurate determination for the number of seconds Lola needs to sign all 96 invitations?
508 seconds
510 seconds
509 seconds
508.8 seconds
9.4 minutes
To find the most accurate determination for the number of seconds Lola needs to sign all 96 invitations, we need to multiply the time it takes Lola to sign one invitation by the number of invitations.
First, we need to convert the time it takes Lola to sign one invitation from seconds to tenths of a second. Since Lola's stopwatch measures time to tenths of a second, we can represent 5.3 seconds as 53 tenths of a second.
Now, we multiply the time taken to sign one invitation (53 tenths of a second) by the number of invitations (96):
53 tenths of a second * 96 invitations = 5088 tenths of a second
To convert this back to seconds, we divide 5088 tenths of a second by 10:
5088 tenths of a second / 10 = 508.8 seconds
Therefore, the most accurate determination for the number of seconds Lola needs to sign all 96 invitations is 508.8 seconds. Hence, the correct option is 508.8 seconds.
