Answer:
15 seconds
Step-by-step explanation:
every minute is 60 seconds
this means that you multiply 60 by 1/4 or divide 60 by 4
when you divide 60 by 4 you get 15
this is how
you can put 4 into 6 one time
so the first digit is 1
the left over is 2
then you drop down the 2
you get 20
4 can go into 20 give times
this means that the answer is 15
