Answer:
the percent of change is \(32.48\%\)
Step-by-step explanation:
Step 1
Convert the time in seconds
\(7:45=7*60+45=465\ sec\)
\(5:51=5*60+51=351\ sec\)
we know that
\(351\ sec\) ----> represent the \(100\%\)
Step 2
the change of the time is equal to
\(465\ sec-351\ sec=114\ sec\)
Step 3
by proportion
find the percent of change
\(\frac{100}{351}=\frac{x}{114} \\ \\x=114*100/351\\ \\x=32.48\%\)
