Answers
Given :-
A 100 meters long train takes 6 seconds to cross a tree .
Required to find :-
- Time taken by the train to cross a 400 meters long bridge
Formulae used :-
Solution :-
Given that :-
A 100 meters long train takes 6 seconds to cross a tree
we need to find the time taken by the train to cross a 400 meters long bridge .
Let's consider given information as case - 1
So,
Length of the train = 100 meters
Distance = Length of the train
Distance = 100 meters
Time = 6 seconds
Using the formula ,
So,
Hence,
Case - 2
Length of the bridge = 400 meters
Distance = Length of the bridge
Distance = 400 meters
Speed =
using the formula ,
✰ Correct Question ✰
⋄ A 100m long train takes 6s to cross a tree.
What will the time taken by the train to cross a 400m long bridge.
✰Answer:-
___________________
✰Given:-
⋄ 6 second is taken by 100m train to cross a tree.
⋄ Here, the length of train is 100m its means that distance traveled by train is 100m.
⋄ Here, another distance =400m
✰To Find:-
⋄ Time taken by train to cross 400 m long bridge??
✰Solution :-
⋄ We know that,
➧ Speed (S) = Distance(d) /Time (t)
➧ S = 100/6
➧ S = 50/3= 16.6m/s
Now,
⋄Speed of train =16.6 m/s
⋄ Distance covered by train =400m.
➧ Time = Distance/ speed
➧ Time = 400/16.6
➧ Time = 24 sec.
