and i also want to know if i can file the 85 dollars for fingerprint together with the form i 485
Depends on if you're eligible to file the I-485 and the filing fee is $1070 in total not just 85 dollars.

The time it takes to approve the I-130 depends on what category of family member you're in. If you're an immediate relative of a U.S. citizen, it should be relatively fast. If you're someone who will have to wait for a visa to become available, it will likely take more than a year. If you qualify to adjust status with the I-485, you'll submit a payment with it for $1,070. This includes the $85 biometrics fee.

It is hard to tell these days because there are now delays in processing petitions and applications. Even their case status website now contains a warning about delays. In the past, it used to be between 3 and 6 months. And yes, you can combine the biometric and I-485 fees for a total of $1,070. You could have reduced the time by filing the I-130 and I-485 together in the first place, assuming that the petitioner is a US citizen.
