Answer:
Bridge = 300 m
Speed = 10 m/s
Step-by-step explanation:
If a goes past you in 10 seconds, it means the train has speed of
100 m/ 10 seconds as it is 100 m long
<u>The speed in m/s is:</u>
Then it take 3 times of 10 seconds to cross the bridge, so
<u>The length of the bridge is:</u>
we are given

Since, we have to solve for t
so, we will isolate t on anyone side
divide both sides by 3

now, we can take ln both sides

we can simplify it

divide both sides by 4ln(r)
