Question: top-left: conversion table with bullet points:
1 in = 2.54 cm
1 m = 39.4 in = 3.28 ft
1 kg = 2.21 lb
1 mi = 1609 m = 1.609 km = 5280 ft
1 ft = 12 in
1 yd = 3 ft
1 hr = 60 min = 3600 s
top-right: Use the given conversions to convert 17.8 km into ft.
center-right: 46,700 ft
58,400 ft
101,000 ft
47,100 ft
1. **State the problem:** Convert $$17.8\text{ km}$$ into feet (ft) using the given conversion factors.
2. **Identify relevant conversions:**
- $$1\text{ mi} = 1.609\text{ km}$$
- $$1\text{ mi} = 5280\text{ ft}$$
3. **Set up the conversion:**
We want to convert $$17.8\text{ km}$$ to miles first, then convert miles to feet.
4. **Convert kilometers to miles:**
$$17.8\text{ km} \times \frac{1\text{ mi}}{1.609\text{ km}} = \frac{17.8}{1.609}\text{ mi}$$
5. **Calculate miles:**
$$\frac{17.8}{1.609} \approx 11.066\text{ mi}$$
6. **Convert miles to feet:**
$$11.066\text{ mi} \times 5280\text{ ft/mi} = 11.066 \times 5280\text{ ft}$$
7. **Calculate feet:**
$$11.066 \times 5280 = 58474.48\text{ ft}$$
8. **Round the answer:**
$$58474.48 \approx 58,400\text{ ft}$$
**Final answer:** $$17.8\text{ km} = 58,400\text{ ft}$$
