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. |

60 km/3600 sec = 0.016667.
0.016667 km/sec*9 sec = 0.15 sec.
0.15 sec*1000 meter = 150 meter.
0.016667 km/sec*9 sec = 0.15 sec.
0.15 sec*1000 meter = 150 meter.

Answer = sec/speed*1000 (i.e. - multiplied with 1000 to convert to metres )
=9/60*1000 = 150m
=9/60*1000 = 150m

Conversion formula for km/hr into m/sec = 5/18.
Conversion formula for m/sec into k/m = 18/5.
Conversion formula for m/sec into k/m = 18/5.

Time = Distance/Speed.
From this Distance = Time*Speed.
= 9*(60*(5/18)) = 149.9999.
= 150.
From this Distance = Time*Speed.
= 9*(60*(5/18)) = 149.9999.
= 150.

Convert km to m - 60000.
Convert hr to sec - 3600.
60000/3600 = 16.666(speed)*9 (time) = 150.
Convert hr to sec - 3600.
60000/3600 = 16.666(speed)*9 (time) = 150.

Answer = (sec/meter)*1000(multiple with 1000 to convert to speed).
Speed = 9/150*1000 = 60.
Speed = 9/150*1000 = 60.

How to calculate please explain clearly.
= (60 x 5/18) x 9.
And the 5/18 how to multiple.
= (60 x 5/18) x 9.
And the 5/18 how to multiple.

Length of train = speed * time.
= 9 * 60 * 5/18(converting km/hr into m/sec).
= 150 meters.
= 9 * 60 * 5/18(converting km/hr into m/sec).
= 150 meters.
