Answer:
Apologies for the incorrect answer in the previous response. Let's recalculate the correct answer.
Given:
Length of the train = 125 m
Length of the platform = 175 m
Speed of the train = 90 km/hr
First, let's convert the speed from km/hr to m/s:
90 km/hr = (90 * 1000) m/3600 s ≈ 25 m/s
The train needs to clear a distance equal to the length of the train and platform combined. So, the total distance the train needs to travel is:
Total distance = Length of train + Length of platform = 125 m + 175 m = 300 m
To find the time it takes for the train to travel this distance, we use the formula:
Time = Distance / Speed
Time = 300 m / 25 m/s = 12 seconds
Therefore, the correct answer is that it will take the train 12 seconds to clear the platform.
Answer:
Time = Speed ÷ Distance
× = 90 ÷ 175
x = 1.94
