Question

The speed of an electric locomotive is 90kmh .express this speed in m/s with method​

Answer 1

24.3 m/s

Step-by-step explanation:

1 kmh = 0.27 m/s, that makes a conversion ratio of 0.27/1kmh

`(90 kmh)/(1)` x
`(0.27 m/s)/(1 kmh)`

The "kmh" n the top and bottom cancel out. And then you just multiply the top 90 x 0.27 and the bottom 1 x 1 to get

`(24.3 m/s)/(1)`

and since its over 1 its just 24.3 m/s
