Unit rate for 320 yards in 8 minutes

40 yards per minute

Step-by-step explanation:

you write out 320 yards/8 minutes. you write it as a fraction (320 yeards over 8 minutes). you want to find the number of yards per minute. to do that you want to make 8 minutes 1 minute. so you do 8 divided by 8. 8 divided by 8 equals one. what you do to the bottem of a fraction you do to the top and vice versa. so you do 320 divided by 8 and get one. you want to write your answer as a fraction so as 40 yards/1 minute (40 yards over 1 minute). always use units because teachers dock points if you don't.
