Kipish [7]

Answer:

4560

Step-by-step explanation:

Well, first we need to understand how different time formats (for lack of a better word) are related in terms of seconds.

1 minute has 60 seconds

I hour has 3600 seconds

1 day has 86400 seconds

1 week has 604800 seconds

Now, with this information at hand, you can find out how many seconds are in X minutes or X days or X months or a year (and so on).

As for your question, we know that one minute has 60 seconds therefore 76 minutes will have (76x60) seconds
