11. The speed of light is about 300,000 km/s.

This question deals with various conversions in mathematics, including kilograms to pounds, miles to kilometers, kilometers per hour to miles per minute, cm to inches, grams to micrograms, ounces to milliliters, inches to mm, and a speed problem involving a cheetah.

Explanation:

1. To convert 46.4 kg to lbs, you multiply by 2.20462, giving approximately 102.29 lbs.
2. To convert 7 miles to kilometers, you multiply by 1.60934, giving approximately 11.26 km.
3. To convert 70 kilometers per hour to miles per minute, you first convert km to miles (muliplying by 0.621371), then convert hours to minutes (dividing by 60), giving approximately 0.7266 miles/minute.
4. To convert 25 kg to pounds, you multiply by 2.20462, giving approximately 55.12 lbs.
5. 30 inches to mm is achieved by multiplying by 25.4, giving 762 mm.
6. To convert 8 cm to inches, you divide by 2.54, giving approximately 3.15 inches.
7. To convert 8 grams to micrograms, you multiply by 1,000,000, giving 8,000,000 μg.
8. To convert 900 g/day to lbs/hour, you first convert grams to lbs (dividing by 453.592), then convert days to hours (dividing by 24), giving approximately 0.0823 lbs/hour.
9. For the cheetah, we need to find its speed. Distance (in miles) = 300 ft x 0.000189394

= 0.05682 miles,

time = 2.92 sec/3600

= 0.0008111 hr.

Then, speed (distance/time) is approximate 69.99 miles/hour.
