Answer 1

Answer:

l=1620 km

Step-by-step explanation:

when two particles are moving opposite to each other

then, t=l/v1+v2

l=9/120+60

l=1620km.

Answer 2

Answer:

length of the train is 0.18kms

Step-by-step explanation:

distance=speed×time

0.27+length of train = 180 × 0.0025

length of train=0.45-0.27
