What distance in km would you have covered if you travelled at a speed of 72 km/H for 2 hours and 30 minuits? ​

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?

Ibelieve it's a. 2.2 - x = -10.85 (plz tell me if it's right : ) )
