if a train with a speed of 60 km per hour crosses a pole in 30 seconds what is the length of the train in metres
Answers
Answer:
The length of the train is 500 m.
Step-by-step explanation:
We know that when a train crosses a pole ,it covers the distance which is equal to its length.
Speed of the train =60 km. / hr.=(60 × 1000 ) / 3600 m/sec.
=50 / 3 m. /sec.
Time taken =30 sec.
Length of train =distance= speed × time
= (50 /3) ×( 30)
=500 m.

Answer:
The length of the train will be approximately 500.1 m
Step-by-step explanation:
Here the speed is given to be 60 km/hr
We will first convert the speed into m/s
To convert km/hr into m/s, we will have to multiply the number by 5/18
60 km/hr = 60 × (5/18)
= 300/18
= 16.666 m/s
≈ 16.67 m/s
The time is given to be 30 seconds
We have to find the length of the train
speed = distance/time
16.67 = distance/30
distance = 16.67 × 30
= 500.1 m
