Answer:
2.9891
Step-by-step explanation:
Data provided in the question:
Frequency observed by observer, f₀ = 455 Hz
Beats heard by the Ballot = 3 beats/s
Now,
Speed of the sound, V = 343 m/s
Also,
Beats heard = 
here,
v is the speed of the train moving towards the observer
thus,
4 = 
or
= 4 + 455
or
156065 = 459( 343 - v)
or
340.0109 = 343 - v
or
v = 343 - 340.0109
v = 2.9891
I think is A but please make sure before going with that answer
