Answer:

\(8.48\ minutes\)

Step-by-step explanation:

we know that

it takes Lola \(5.3\) seconds to sign her full name

so by proportion

Find how many seconds take Lola  to sign \(96\) invitations

\(\frac{5.3}{1}\frac{seconds}{invitation}=\frac{x}{96}\frac{seconds}{invitations} \\ \\ x=96*5.3\\ \\x= 508.8\ seconds\)

Convert seconds to minutes

Remember that

\(1\ minute=60\ seconds\)

so

\(508.8\ seconds=508.8/60=8.48\ minutes\)
