For this case the first thing you should know is the following conversion:
[tex]1 minute = 60 seconds
[/tex]
We can then make the following rule of three:
1 minute ----------> 60 seconds
3/4 minutes -------> x
From here, we clear the value of x.
We have then:
[tex]x = (3/4) * (60)
x = 45 s[/tex]
Answer:
there are 45 senconds in 3/4 of a minute
