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 |

Change the km/hr to m/sec using:
0.278*60=16.68;
16.68*9=150.12,
Answer is near the 150.
0.278*60=16.68;
16.68*9=150.12,
Answer is near the 150.

First we converted into m/s to speed.
So length = speed *time.
So, length =50 * 3 = 150.
So length = speed *time.
So, length =50 * 3 = 150.

Similarly 60 km/hr = 60 x 5/18 m/sec.
Kindly explain how this line how 150 meters came?

There for 9seconds convert into hours.
60km convert into meters.
9/3600 * 60000 = 150.
60km convert into meters.
9/3600 * 60000 = 150.

Simple and.
Speed = distance/time.
60 = distance/9.
Distance = 60 * 9,
Distance = 150.
Speed = distance/time.
60 = distance/9.
Distance = 60 * 9,
Distance = 150.

Velocity = distance/time.
Distance = velocity*time.
= 60*(0.27)(9).
= 150 m/s.
Distance = velocity*time.
= 60*(0.27)(9).
= 150 m/s.

1hr = 60Km.
3600sec = 60000 m.
1sec = 60000/3600 = 50/3.
9 sec = (50/3)*9 = 150m.
3600sec = 60000 m.
1sec = 60000/3600 = 50/3.
9 sec = (50/3)*9 = 150m.

I have one doubt.
Why don't you change 9sec into hours and then calculate distance?
