= | |
50 | m/sec. |
| 18 | 3 |
Length of the train = (Speed x Time).

from the above statement:
60,000 m is crossed in=>3600 s.
? m is crossed in=> 9 s.
60000/x => 3600/9.
Do a normal cross-division method to find x. That's the answer.

Length of the train = 9*50/3 = 150.
If train crosses pole in 20 seconds.
Length of the train = 20*50/3?
Is the length of the train depend on the time the it crosses the pole? Please answer.

10/36 = 5/18.
If both numerator and denominator can divide by a Single number, then you can divide it.
Here in above problem 10 and 36 both are dividing by 2, that's why the answer is 5/18.

Hey, guise your answer is really good. But I have 1 prob how to convert km/hr 1000/3600. In that form 5/18.
But thanks to Arvind. I understand. How to convert. Really thanks again Arvind.

@All.
Let me explain in the short.
1st look at the options is in meters so 1 kms = 1000m.
1000/60 (speed) =16.66666 per sec,
Length = speed × time.
So, the answer is 16.6666 × 9 = 150m.

*Simple solution*
We know that,
1) 60km/1hr= 60000m/3600sec , (1hr=3600sec).
*Calulation = 60000/3600 = 16.66m/sec.
16.66x9 = 149.99 = 150m answer.
