If 1 m = 3.28 ft, then use dimensional analysis and the given information to convert 100 km to feet.

Answer 1

To convert 100 km to feet, we can use dimensional analysis as follows:

1 km = 1000 m (since 1 km is equal to 1000 meters)
1 m = 3.28 ft (given information)

So, the conversion factor from km to ft is:

(1000 m / 1 km) * (3.28 ft / 1 m) = 3280 ft

Therefore, 100 km is equal to 3280 ft.
