Answer 2

Answer:

576 km

Step-by-step explanation:

Formula used is Distance= Speed ×Time.......(1)

Train covers 432 km in 9 hours i.e. D= 432 , T= 9  

substitute D= 432 , T= 9  in formula (1), we get

432=S×9

432/9=S

S=48

Now distance covered by train in 12 hours (T=12) is

D= S×T

 =48×12

  =576 km
