Answer:
53km/h
Explanation:
length of first train=280m
length of second train=370m
total distance traveled by other train=280+370=650m
first train also covered same distance.
speed of first train=53km/h
in m/s speed of first train=53*5/18=265/18
time taken=650*18/265s
therefore speed of second train=650*265/(650*18)=265/18m/s=265*18/(5*18)=53km/h
