one lap around a dirt track is 1/3 of a mile. It takes Bruce 1/9 hour to ride one lap. What is Bruce's Unit rate, in miles around the track?
He does (1/3) lap in (1/9) hr.....so......multiplying both by 9, we have.....
3 laps in 1 hour ..... and 3 laps x (1/3) mile per lap = 1mile.....so he travels at.....
1 mile per 1 hour
you have to divide them both and if u can simplify it hope this helped ;)
