We are provided with the information that a train is running at the speed of 60 km/hr crosses a pole in 9 seconds and are asked to find the length of the train.
Using the given information we have —
speed of train = 60 km/hr
time taken = 9 sec
length of the train = ?
Let's call 'x' be the length of the train.
We know that —
Speed = Distance/Time
Value of speed is 60 km/hr and time is 9 sec. Before substituting these values first convert km/hr into m/s. To do so, multiply the value by 5/18. So,
Answers & Comments
Answer:
150 m
Step-by-step explanation:
Speed = 60km/hr
= 60*1000/3600 m/s = 50/3 m/s
Time = 9s
Length of train = speed * time
= 50*9/3
= 150 m
Verified answer
Answer:
length of the train = 150 m
Step-by-step explanation:
We are provided with the information that a train is running at the speed of 60 km/hr crosses a pole in 9 seconds and are asked to find the length of the train.
Using the given information we have —
Let's call 'x' be the length of the train.
We know that —
Value of speed is 60 km/hr and time is 9 sec. Before substituting these values first convert km/hr into m/s. To do so, multiply the value by 5/18. So,
Now, substitute the values,
[tex]\implies[/tex] 50/3 = x/9
Multiply by 9 on both sides,
[tex]\implies[/tex] 50/3 × 9 = x/9 × 9
[tex]\implies[/tex] 50/3 × 9 = x
[tex]\implies[/tex] 50 × 3 = x
On solving we get,
[tex]\implies[/tex] 150 = x
[tex]\implies[/tex] x = 150 m
Hence, the length of the train will be 150 m.
