Answer :
2 weeks is equal to 1,209,600,000 microseconds.
554 m^4 / (day ⋅ kg) is approximately equal to 1148992.24662822 ft^4 / (min ⋅ lbm).
38.1 ft/s = 0.8701833668556701 km/h.
a. To convert 2 weeks to microseconds:
1 week = 7 days
1 day = 24 hours
1 hour = 60 minutes
1 minute = 60 seconds
1 second = 1,000,000 microseconds
2 weeks = 2 * 7 * 24 * 60 * 60 * 1,000,000 microseconds
b. To convert 554 m^4 / (day ⋅ kg) to ft^4 / (min ⋅ lbm):
1 m = 3.28084 ft
1 day = 24 hours
1 hour = 60 minutes
1 kg = 2.20462 lbm
First, convert m^4 to ft^4 by multiplying by (3.28084)^4.
Then, convert day to minute by multiplying by 24 * 60.
Finally, convert kg to lbm by multiplying by 2.20462.
554 m^4 / (day ⋅ kg) = (554 * (3.28084)^4) ft^4 / (min ⋅ lbm)
c. To convert 38.1 ft/s to kilometers/hour:
1 mile = 1.60934 kilometers
1 hour = 3600 seconds
1 foot = 1/5280 miles
First, convert ft/s to miles/hour by dividing by 5280.
Then, convert miles/hour to kilometers/hour by multiplying by 1.60934.
Therefore, 38.1 ft/s = (38.1 / 5280) * 1.60934 kilometers/hour
