4. A plane's average speed between two cities is 200 m/s. If the trip takes 2.5 hours, how far does the plane fly?​

Step-by-step explanation:

Average speed (S) = 200 m/s

Time taken (t) = 2 .5 hours = 2.5 *60*60 = 9000 sec

Now distance travelled (d) = ?

We know

The distance travelled by a body per unit time is

speed so

S = d / t

200 = d / 9000

d = 9000 * 200

d = 1800000 meters.

The plane flies 1800000 meters.

180

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
