keeping in mind that 250 days is not even a year, since there are 365 days in a year, assuming so, then 250 days is really 250/365 years.

I rounded it to 150.
You could round 15.217 down to 15 and 9.54 up to 10 and then multiply 15 x 10 = 150. But you could also multiply 15.217 x 9.54 to get 145.17018 and round that up to 150 because any number that ends with 5 or higher rounds up.
