To find the superhero's speed in miles per hour, we can use the formula:
\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]
- Distance from New York to Los Angeles: 2,450 miles
- Time taken: 30 minutes. We need to convert this into hours:
\[ 30 \text{ minutes} = \frac{30}{60} \text{ hours} = 0.5 \text{ hours} \]
- Now, calculating the speed:
\[ \text{Speed} = \frac{2,450 \text{ miles}}{0.5 \text{ hours}} = 4,900 \text{ miles per hour} \]
Thus, the superhero is flying at a speed of 4,900 miles per hour.
The correct answer is C. 4,900.
