Answer:

hey here is your answer

pls mark it as brainliest pls

Step-by-step explanation:

so here distance(need to be covered ie d1)=130 m=0.13 km

speed of train=50 km/h

length of train (d2)=120 m=0.12 km

so total distance =d1+d2

=0.13+0.12

=0.25m

so we know that

speed=distance/time

50=0.25/time

time=0.25/50

=0.05 hours

so converting hours to minutes

we know that

1 hr=60 mins

1 min=60 secs

hence 1 hour=60×60=3600 secs

so similarly

0.005 hours=0.005×3600

= 18 seconds
