1.
A train running at the speed of 60 km/hr crosses a pole in 9 seconds. What is the length of the train?
Answer: Option
Explanation:
| Speed = |  |
60 x | 5 |  m/sec |
= | |
50 | m/sec. |
| 18 | 3 |
Length of the train = (Speed x Time).
 Length of the train = |
|
50 | x 9 | m = 150 m. |
| 3 |

The speed of train in 1sec =(60*5)/18=16.66666666666667 m/sec,
As we know that an object or a thing can be crossed with the length of a train
we took 9sec then
The length of train = 16.66666666666667 * 9 = 150 m.

60 * 60 = 3600,
1000/3600 = 5/18,
60Km/hr.
1km = 1000m,
1hr = 60min.
1sec = 60sec.
1000/3600 = 5/18,
60Km/hr.
1km = 1000m,
1hr = 60min.
1sec = 60sec.

1km = 1000m
1h = 3600sec
Length = speed/time.
S = 1000/3600 = 5/18.
6 * 5/18 = 16.66667.
16.66667m/sec * 9 = 150m.
1h = 3600sec
Length = speed/time.
S = 1000/3600 = 5/18.
6 * 5/18 = 16.66667.
16.66667m/sec * 9 = 150m.

600 % 36 = 16.67.
16.67 * 9 = 150.
16.67 * 9 = 150.

Time = Length of the train/Speed of the train.
Time is in seconds, do speed should be in metres/Seconds.
60 km/hr = 60 × 5/18 m/s = 50/3 m/s.
9 seconds = length/50/3.
9 × 50/3 = length.
length = 3 × 50 = 150 metre.
