a train travelling at 30 m / s takes 3 s to pass the child. what is the length of the train?
30 m/s * 3 s = ? m
90m
To find the length of the train, we can use the equation:
Length of the train = Speed of the train × Time taken to pass the child
Given information:
Speed of the train = 30 m/s
Time taken to pass the child = 3 s
Using the equation, we can substitute the values:
Length of the train = 30 m/s × 3 s
Now, let's calculate:
Length of the train = 90 meters
Therefore, the length of the train is 90 meters.
To find the length of the train, we can use the formula:
Length = Speed × Time
Given that the train is traveling at a speed of 30 m/s and it takes 3 seconds to pass the child, we can substitute these values into the formula:
Length = 30 m/s × 3 s = 90 m
Therefore, the length of the train is 90 meters.
