An airplane flies 1650 miles in 2 hours 30 minutes. What is its average speed in miles per hour? pls help i’m doing a quiz and i have no idea what i’m doin

v = 660 miles per hour

Explanation:

Given that,

The distance covered by the airplane is 1650 miles

Time taken by airplane is 2 hours 30 minutes

We need to find the average speed of the airplane. The total distance covered divided by total time taken is called the average speed of an object.

We know that,

1 hour = 60 minutes

⇒ 30 minutes = 0.5 hour

So,

Hence, the average speed of the airplane is 660 miles per hour.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
