The answer is A because it has the most amount of speed, the plane has the same speed but doesn't tell you for what amount of time is the speed so what if the plane traveled 15 per 2 hours or 3 obviously the truck is going faster and it if said 15 miles per minute then it would obviously be the plane but since it doesn't specify then the truck would be you rmost likely answer
Hope this helps

scientific investigation is the quest to find an answer to a question using scientific method.
Explanation:
Answer:
5.74 gm
Explanation:
First, use the ideal gas law PV = n RT
to find the number of moles, then multiply by 28 g/ mole
PV = n RT T must be in Kelvin R = 8.314463 L kPa/(K - Mol)
( make sure you use the R with the correct units!!)
182 kPa * 3 L = n (8.314463 ) ( 273.15+47.2)
solve for n = .205 moles
.205 mole * 28 g/mole = 5.74 gm
