Just use cast to integer arithmetic:
MINTING_VELOCITY = 2
ACCURACY_RATIO = 1000000
And the formula converts to: A x t x MINTING_VELOCITY / ACCURACY_RATIO

If the MAIN contract inherits from RandomNumberConsumer making editDna internal should be enough.
// Declare contract as abstract
abstract contract RandomNumberConsumer is VRFConsumerBase {
// Forward declaration
function editDna(uint randomN, uint carId, bytes32 requestId) internal virtual;
constructor() VRFConsumerBase(..) public {

It looks like your contract doesn't have LINK funds to perform the random number generation. Note this require in function getRandomNumber():
require(LINK.balanceOf(address(this)) >= fee, "Not enough LINK - fill contract with faucet");
In the same documentation from this example, there is an explanation on how to fund this contract with LINKs ...

This line of code ensures that the passed tokens are sorted deterministically (e.g. token with lower address first), so that the pair address can be retrieved in a single lookup:
(address token0, address token1) = tokenA < tokenB ? (tokenA, tokenB) : (tokenB, tokenA);
require(token0 != address(0), 'UniswapV2: ZERO_ADDRESS');
require(getPair[token0]...

You can get ABI json from etherscan API like below.
var Web3 = require('web3');
var web3 = new Web3(new Web3.providers.HttpProvider());
var version = web3.version.api;
$.getJSON('https://api.etherscan.io/api?module=contract&action=getabi&address=0xfb6916095ca1df60bb79ce92ce3ea74c37c5d359', function (data) {
var contractABI = "";...
