An airplane is traveling at a speed of 200 km/h. compute the speed of the airplane in m/s. a) 3.3 m/s b) 33.3 m/s c) 55.6 m/s d) 111.20 m/s

Given the speed is 200 km /hr

use 1 km  = 1000 meter

1 hr = 3600 seconds

so

simplifies to

so option C

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

don't know what that says sorry i can't you

step-by-step explanation:

idk what it says
