In 4.5 billion years, the amount of mass lost is 1.41912 * 10¹⁷ kg.
<h3>
Equation</h3>
An equation is an expression used to show the relationship between two or more variables and numbers.
Given that:
Io loses about a ton (1000 kilograms) of sulfur dioxide per second to Jupiter's magnetosphere.
In 4.5 billion years, amount of mass lost = 1000 kg/s * (4.5 * 10⁹ * 365 * 60 60 * 24) = 1.41912 * 10¹⁷ kg.
In 4.5 billion years, the amount of mass lost is 1.41912 * 10¹⁷ kg.

Answer:
Lindsey biked 45 miles for 3 hours at 15 mph and walked 8 miles for 2 hours at 4 mph.
Explanation:
Speed = distance/time
Let the distance that Lindsey biked through be x miles and the time it took her to bike through that distance be t hours
Then, the rest of the distance that she walked is (53 - x) miles
And the time she spent walking that distance = (5 - t) hours
Her biking speed = 15 mph = 15 miles/hour
Speed = distance/time
15 = x/t
x = 15 t (eqn 1)
Her walking speed = 4 mph = 4 miles/hour
4 = (53 - x)/(5 - t)
53 - x = 4 (5 - t)
53 - x = 20 - 4t (eqn 2)
Substitute for X in (eqn 2)
53 - 15t = 20 - 4t
15t - 4t = 53 - 20
11t = 33
t = 3 hours
x = 15t = 15 × 3 = 45 miles.
(53 - x) = 53 - 45 = 8 miles
(5 - t) = 5 - 3 = 2 hours
So, it becomes evident that Lindsey biked 45 miles for 3 hours at 15 mph and walked 8 miles for 2 hours at 4 mph.
Explanation:
If it doesn't specify vertical or horizontal, that means it wants you to find the total velocity. You can do that using Pythagorean theorem:
v² = vₓ² + vᵧ²
A close representation of the moons motion around earth is that it moves around the earth once in 27.3 days. the moons average movement is 13.2 degrees per day so around 92 per week.
