Respuesta :
For this case we have that by definition, one minute equals 60 seconds. Then, we make the conversion:
[tex]\frac {60 \ s} {1 \ m} * 3 \ m = 180 \ s[/tex]
Thus, 3 minutes equals 180 seconds.
Now:
[tex]180 + 48 = 228[/tex]
So, it took Jason 228 seconds to complete a practice page in class.
Answer:
228 seconds
