Question

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

Answer 1

Answer:

24.3 m/s

Explanation:

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

$\frac{90 kmh}{1}$ x $\frac{0.27 m/s}{1 kmh}$

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

$\frac{24.3 m/s}{1}$

and since its over 1 its just 24.3 m/s
