Which property of inequalities states that if x ≤ 5 and 5 ≤ y , then x ≤ y?

The answer is: The transitive property.

Inequalities express the relative size between two values/numbers.

The transitive property of inequalities states that there's a way to relate two or more inequalities when they have at least a common value, and we can use it to create a relationship with a third or more values/variables.

For your statement, we have

A common value which is 5

Two inequalities expressing a relative size between two variables and a common value which is 5:

So, the inequalities are telling us that the common value (5) is higher or equal than x

and, the variable y is higher or equal than  5

So, using the transitive property we can safely assume that, y is higher or equal, than x

Have a nice day!

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
