Answer:
121
Step-by-step explanation:
66+44=110
2+9=11
110+11=121
30 inches @ 500 rpm = 15,000 inches per minute
15,000 inches per minute = 900,000 inches per hour (multiply by 60)
1 mile = 5,280 feet (google-able fact you shouldn't have to memorize)
1 foot = 12 inches (you probably already know this)
900,000 inches = 75,000 feet (divide by 12)
75,000 feet = 14.20454545454545. . . miles (divide by 5280)
Linear velocity in miles per hour is 14.20454545454545. . . miles per hour.
