How many days are in four years and fifteen weeks?

Answer 1

the answer is 1565 days

a year has 365 days in it and a week has 7. 4 years have 1460 days because

365 * 4 = 1460 and 15 weeks have 105 days because 15 * 7 = 105.

1460 + 105 = 1565. if one of the years was a leap year then the answer will be 1564.
