Step-by-step explanation:
12.25 miles in 45 minutes.
How far in 60 minutes?
Set up a proportion: 12.25/45=x/60
45x=735
x=16.3333...
Therefore, Manuel can go 16 1/3 miles in one hour.
I hope this helped and have a good rest of your day!

Answer:
180 meters
Step-by-step explanation:
100yd field is 90 meters so a 200yd field is 180 meters
320 = 2x² - 12x as when there are an unknown number of rows there are 320 seats.
0 = 2x² - 12x - 320
0 = x² - 6x - 160
0 = (x - 16)(x + 10)
for this to = 0 one bracket must equal 0
therefore x = 16 or x = -10
not a negative number of rows.
Therefore must be 16.
