Question

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 minutes Lola needs to sign all 96 invitations?

Answer 1

answer choices (please post these next time)

A. 3.3 minutes
B. 3.3125 minutes
C. 8.48 minutes
D. 8.5 minutes

Answer 2

first step is to do the calculations: 96 invitations, at 5.3 seconds each ---> multiply 96 * 5.3 to get the total time, in seconds, to sign the invitations. since there are 60 seconds/min, divide the time in seconds by 60 to get minutes.

second step: rounding according to the accuracy of the stopwatch. since the stopwatch measures to the tenths place, you'll also have to round your answer to the tenths place
