Answer 1

Answer:  Option 'C' is correct.

Step-by-step explanation:

Total number of invitations = 96

Time taken to sign her full name = 5.3 seconds

Total time she needed to sign in 96 invitations is given by

$96\times 5.3\\\\=508.8\ seconds$

And we know that

$1\ minute=60\ seconds\\\\508.8\ seconds=\frac{508.8}{60}=8.48\ minutes$

So, Lola will be able to finish signing all the invitations after 8.84 minutes.

Hence, Option 'C' is correct.
