60Km/hr.
1km = 1000m
1hr = 60min.
1sec = 60sec.
Got it.
1000 ÷ 60×60.
The Formula is
Distance=speed×Time
Listen here,
D = S×T,
S = 60,
T = 9.
60 × 5 ÷ 18 × 9.
[150m].
1km = 1000m
1hr = 60min.
1sec = 60sec.
Got it.
1000 ÷ 60×60.
The Formula is
Distance=speed×Time
Listen here,
D = S×T,
S = 60,
T = 9.
60 × 5 ÷ 18 × 9.
[150m].

@Raj
To convert km to metre;
Km - m = × 5/18.
m - km = × 18/5.

To find the length we can use the formula is length = speed * time.
Speed = 60km/hr
Pole = 9second
The length of the train would be 60*9/3600 = 0.15km or 150 meters.
Speed = 60km/hr
Pole = 9second
The length of the train would be 60*9/3600 = 0.15km or 150 meters.

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

Length = speed * time,
L=60 * 5/18,
= 50/3 * 9,
= 150 meters.
L=60 * 5/18,
= 50/3 * 9,
= 150 meters.
