Answer 1

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):

$\bigtriangleup Time=Dinner \ Time-Arrival Time\\\\=5:51-5:34\\\\=(51-34)\ minutes\\\\=17\ minutes$

-Having calculated this time difference, we convert it into seconds using the ratio 1 minute =60 seconds:

$\bigtriangleup Time=17\ \times 60\ seconds\\\\=1020\ seconds$

Hence, her dinner is ready 1,020 seconds after arriving home.,
