60 x | 5 |  m/sec |
= | |
50 | m/sec. |
| 18 | 3 |

Here L = speed(m/s) x time(s).
= 150m.
= 150m.

So the pole been exposed to the train for 9 sec, in a speed of 60km/hr, which is equivalent to covering a distance equals speed (m/s) x time (s) = 150m.

Length = Speed × Time.
First, convert the speed from km/hr to m/s:
60 km/hr = 60 × (5/18) m/s = 50/3 m/s.
Then, multiply by the time (9 seconds):
Length = (60 × 5/18) × 9 = 150 meters
First, convert the speed from km/hr to m/s:
60 km/hr = 60 × (5/18) m/s = 50/3 m/s.
Then, multiply by the time (9 seconds):
Length = (60 × 5/18) × 9 = 150 meters
