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?​
ioda

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.
