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. |

For converting km to m 60*1000 = 60000m.
For converting hrs. to sec. 60 * 60 = 3600sec.
60000/3600 = 16.6666.
16.666 * 9 = 150.
For converting hrs. to sec. 60 * 60 = 3600sec.
60000/3600 = 16.6666.
16.666 * 9 = 150.

Given, S = 60 km/hr,
Time(T) = 9 sec and L(T)=?
Speed(S) = (60 * 5/18) = (50/3 m/sec).
L(T) = S * T.
L(T) = (50/3*9)m.
= 150m.
Time(T) = 9 sec and L(T)=?
Speed(S) = (60 * 5/18) = (50/3 m/sec).
L(T) = S * T.
L(T) = (50/3*9)m.
= 150m.

60km/60min = 1km/min.
1km = 1000metres , 1hr = 60mins.
1000m/60min = 16.666667.
16.666667 * 9 = 150metres.
1km = 1000metres , 1hr = 60mins.
1000m/60min = 16.666667.
16.666667 * 9 = 150metres.

1 km = 1000 m,
1 hr has 3600 sec.
So, 1 km/hr = 1000m/3600s = 5/18 m/s.
1 hr has 3600 sec.
So, 1 km/hr = 1000m/3600s = 5/18 m/s.

60*9/18.
50/3.
50/3*9.
= 150 Ans.
50/3.
50/3*9.
= 150 Ans.

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.

60 * 1000m/3600s = 16.66m/s.
So, distance = 16.66 * 9 = 150m.
So, distance = 16.66 * 9 = 150m.
