Answer: The distance is 12.04 miles</span>
Divide distance by time.
Chance the time to a decimal:
33 minutes / 60 = 0.55
Time was 3.55 hours.
Speed = 2840/3.55 = 800 miles per hour
Answer:
214
Step-by-step explanation:
A circle is 360 degrees
Arc EF is 146 degrees
EF + EDF = full circle
146 + EDF = 360
Subtract 146 from each side
146-146 +EDF = 360-146
EDF =214
