Answer:
1,020 seconds
Step-by-step explanation:
-We first subtract the two times to get the time before dinner is ready(after arriving home):
[tex]\bigtriangleup Time=Dinner \ Time-Arrival Time\\\\=5:51-5:34\\\\=(51-34)\ minutes\\\\=17\ minutes[/tex]
-Having calculated this time difference, we convert it into seconds using the ratio 1 minute =60 seconds:
[tex]\bigtriangleup Time=17\ \times 60\ seconds\\\\=1020\ seconds[/tex]
Hence, her dinner is ready 1,020 seconds after arriving home.,
