Answer:
$28,366.90
Step-by-step explanation:
Answer:
177 ft below sea level.
Step-by-step explanation:
Initial altitude of the hot air balloon = 282 below sea level
Rate of rise of balloon = 10 ft / second
Time = 12 seconds
Total rise in 12 seconds = Rate of rise of balloon
Time
= 120 ft
Now, we will have to subtract to find the new altitude.
New altitude = 282 - 120 = 162 ft
Now, it is given that balloon Captain lowers the balloon 15 ft.
To find the final altitude, we will have to add it to the previous altitude.
Therefore, the final altitude = 162 + 15 = <em>177 ft below sea level </em>
It was given that
1 gal = 20 lbs of CO2
1 gal = 25 miles distance
Thus,
15000 miles/year ( 1 gal / 25 miles ) ( 20 lbs CO2 / 1 gal ) = 12000 CO2
<span>If Harry drives 15,000 miles per year, his vehicle will add 12000 pounds of CO2 to the atmosphere.</span>
