Everyone is entitled to a fair trial.
So we know the bus can travel 2,160 miles in 36 hours
to find out how many hours the bus travels in an hour we simply divide the total miles given (2,160) by the total hours given (36)
2160 miles/36 hours = 60 miles
so the average distance the bus travels in 1 hour is 60 miles
