How do i show work for this question? a train travels at an average speed of 67.5 miles per hour. at this speed how far could the train travel in 3.25 hours

First thing you need to convert 67.5 miles per hour to meter per Second
67.5 miles per hour it will be 30.1752 meter per second
Than convert hours to Second
So, 3.25×60×60 = 11700s
Than, we know that v = d/t
30.1752= d/11700
So, d= 30.1752×11700
= 353049.84m

B.-2,3 because it is touch the -3 i think that the answer
