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