Question

The track used by the first successful steam locomotive was 15 300 metres long how many kilometres long was it

Answer 1

Answer:

The length of the track is 15.30 km

Step-by-step explanation:

Length of the track =15300 metres

We know from the Measurement that there are 1000 metres in 1 km

$1000\ \rm m= 1\ \rm km\\\\1\ m=\dfrac{1}{1000}\ \rm km\\\\15300\ \rm m=\dfrac{1}{1000}\times15300\ \rm km\\\\=15.30\ \rm km$

Hence the length of the track in km is calculated
