Misty's surgery lasted 2 1 hr. convert time to seconds?

For this case we must convert 21 hours to seconds!

We have that by definition, 1 hour equals 3600 seconds. Then, making a rule of three we have:

1h ------------> 3600s

21h ----------> x

Where "x" represents the number of seconds equivalent to 21 hours.

Thus, 21 hours represent 75600 seconds.

75600 seconds.

no, x cannot be the same number. in all of them, x is 1. for one input there is another output. g is not a function
