Convert 10 miles into inches:
10 miles = 10*5280 = 52800 feet 633600 inches

(pi)d = (3.14) = 87.92 inches per revolution
633600/87.92 =7206.55 revolution per hour
convert to revolution per min:
7206.55 rev/hr * 1/160 hr/min
120.1 revolution per minute

Question in image. :)
quester [9]

a. f(a) =5a+12

we have 1. a=6

Therefore, where ever we find a we'll substitute in 6

f(6) =5(6) +12

6f=30+12

6f=42

so therefore 1. a=6 will match c on the right

2. a=2

f(2) =5(2) +12

2f = 10+12

2f = 22

therefore 2. a=2 will match a on the right

3. a=4

f(4) =5(4) +12

4f=20+12

4f=32

therefore 3. a=4 will match d on the right

4. a=5

f(5) =5(5) +12

5f=25+12

5f=37

therefore 4. a=5 will match b on the right
