1. Convert the speed from miles per hour to feet per second:
1 \text{ mile} = 5280 \text{ feet}
1 \text{ hour} = 3600 \text{ seconds}
52 \text{ miles per hour} = 52 \times \frac{5280}{3600} \text{ feet per second}
52\times\frac{5280}{3600}=76.2667\text{ feet per second}
2. Use the formula \( t = \frac{d}{v} \) to find the time:
d = 1000 \text{ feet}
v=76.2667\text{ feet per second}
t=\frac{1000}{76.2667}\approx13.11\text{ seconds}
Answer: 13.11 seconds
