time -9 seconds
speed -64km/hr=64000/3600
distance=64000/3600*9=160m
length of train=160m
speed -64km/hr=64000/3600
distance=64000/3600*9=160m
length of train=160m

Answer:
Step-by-step explanation:
ANSWER:-
Given that:-
A train running at a speed of 84 km/h
The train crosses a electric pole at 9 seconds
We need to find the length of the train.
Let's Do!
What we can do here, is first convert the given units into SI units.
84 km/h => m/s
1 metre = 1000 km
1 hour = 3600 seconds
So, we can now multiply 84 with 5/18
It was just a shortcut method, you can use it directly as well.
So, we get:-
mps means metre/second.
Now, we know that
Now, we need is length ie Distance.
So, 23.33*9 = 209.97 metres is the length of the train.
