Answer:
4.09 seconds
Step-by-step explanation:
simplify miles per hour to feet per second how many feet is a mile and how many seconds are in an hour you end up with 88 fps from 60 mph
now simply a football field is 360 feet so 360/88 is 4.09090909 etc
5.71428571429
r = 12
108 = 9r | Given expression
12 = r | Divide both sides by 9. 108 becomes 12 and 9r becomes r.
All of the above
