which funtion represents the number of seconds, s, in d days? (hint: The number of seconds in a day is 24 x 60 x 60 = 86,400.) The function that represents the number of seconds, s, in d days is f(d)

Answer 1

This is a bit of a strange question, but it seems that we want the number of seconds as a function of the number of days. So, we want s(d). To find this we know that there are 24hrs in a day, 60 min in an hr, and 60 s in a min. or in terms of rates:

24 hrs/day

60 min/hr

60 s/min

To get the number of seconds we just need to cancel all units except for s:

s(d) = 60*60*24 * (s/min * min/hr * hr/day) This is incomplete

we see in this expression that all the units cancel except for s and day, therefore we need to multiply by the number of days to get the number of seconds:

s(d) = 60*60*24*d = 86,400*d

and we have our function that represents the number of seconds in d days.
