distance = 20miles
hope that helps :)
If a cross country runner travels at a speed of 10 mph and he runs for 2 hours, 20miles he will have run at the end of the 2 hours.
What is distance?Distance is a description of how far apart two things or points are, either numerically or occasionally qualitatively. Distance can be used to describe a length in physics or to an estimate based on other factors in common usage.
The phrase is widely used metaphorically to refer to a measurement of the degree of distinction between two similar items since spatial intelligence is a rich source of implicatures in human understanding.
distance = speed x time
distance = 10 x 2
distance = 20miles
Therefore, 20miles is the distance.

A gas has a volume of 22. 6L at 3. 6 atm. What is the pressure of the gas at 44. 3L
Answer:
1.837 atm
Explanation:
According to Boyle's Law:
[tex]V_{1} P_{1} = V_{2}P_{2}[/tex]
(22.6L) (3.6atm) = (44.3L) (x)
x = 81.36 /44.3
x = 1.837 atm
This is because Volume and Pressure are inversely proportional. If one increases the other has to decrease.

You are a NASA engineer. You are the chief engineer for the Apollo 13 mission to the moon. The astronauts are running out of oxygen and need to get rid of the excess carbon dioxide. You know that sodium hydroxide (NaOH) has been suggested as a means of removing carbon dioxide from the spacecraft cabin. The filter which they had been using is fully saturated and no longer works. You remember that the astronauts have a 5000. g container of sodium hydroxide on the ship. You also know that sodium hydroxide can be used to remove carbon dioxide.
Use the following reaction: NaOH + CO2 → Na2CO3 + H2O
The astronauts have 2 days left before they land on Earth. You know that there are three astronauts, and each astronaut emits roughly 500. g Of carbon dioxide each day. Is there enough sodium hydroxide in the cabin to cleanse the cabin air of the carbon dioxide, or are the astronauts doomed? SHOW ALL YOUR WORK - DON’T FORGET TO BALANCE THE EQUATION
Guiding Questions: How many grams of CO2 are produced in a day? How many grams of CO2 are produced in both days? How many grams of NaOH do you need to get rid of 3000 g of CO2?
Answer:
We know that there are three astronauts and each one of them emits 500 grams of carbon dioxide each day, so the total carbon dioxide emitted each day.
Explanation:
From the mole ratio of the reaction, there is not enough sodium hydroxide in the cabin to cleanse the cabin air of the carbon
What was of Sodium hydroxide is required?The mass of sodium hydroxide required depends on the mass of CO2 produced by the astronauts.
The mass of CO2 produced by the astronauts is calculated as follows;
Mass of CO2 produced = 3 × 2 × 500 g = 3000 g of CO2
The mass of sodium hydroxide required is calculatedfrom the eqaution of the reaction given below:
[tex]2NaOH + CO_2 → Na_2CO_3 + H_2O \\ [/tex]2 moles of sodium hydroxide reacts with 1 mole of CO2
Molar mass of NaOH = 40 g/mol
Molar mass of CO2 = 44 g/mol
Mass of sodium hydroxide required = 3000 g × 2 × 40/44 = 5454.54 g
Therefore, there is not enough sodium hydroxide in the cabin to cleanse the cabin air of the carbon.
