Step 1:I'll solve this step-by-step using the specified LaTeX formatting guidelines:
Step 2:: Calculate the speed in feet per second
- Speed = $$\frac{100 \text{ feet}}{2 \text{ seconds}} = 50 \text{ feet/second}
- Time taken = 2 \text{ seconds}
Step 3:: Convert feet per second to miles per hour
- First, convert feet to miles: $$\frac{50 \text{ feet}}{1 \text{ second}} \times \frac{1 \text{ mile}}{5280 \text{ feet}}
- Then, convert seconds to hours: \times \frac{3600 \text{ seconds}}{1 \text{ hour}}
Step 4:: Perform the calculation
50 \times \frac{1}{5280} \times 3600 = \frac{180000}{5280} = 34.09 \text{ miles per hour}
Step 5:: Round to the nearest whole number
34 \text{ miles per hour}
Final Answer
C. 34 miles per hour
