A train of 100mt long is moving With constant speed 10m/s calculate time required for the train to cross electric pole and a bridge of 500mt long?​

Answer 1

Question

A train of 100 m long is moving with constant speed 10 m/s calculate the time required for the train to cross electric pole and a bridge of 500 m long?

Solution

Given that, length of train = 100 m

Length of bridge = 500 m

The train of length 100 m is moving with a constant speed of 10 m/s.

So, speed = 10 m/s

We have to find the time required for the train to cross electric pole and a bridge of 500 m long.

Now,

Total length (distance) = (100 + 500)m = 600 m

And speed is 10 m/s

We know that,

Speed = Disatnce/Time

→ 10 = 600/Time

→ Time = 600/10

→ Time = 60 s

Therefore, the time required for the train to cross the electric pole and a bridge of 500 m long is 60 seconds.

Answer 2

★ QuestioN :

A train of 100 m long is moving with constant speed 10 m/s calculate the time required for the train to cross electric pole and a bridge of 500 m long?

$\rule{200}{1}$

★ SolutioN :

Length of train = 100 m

Length of the bridge = 500 m

Speed = 10 m/s

As, we have to find the total time required to cover the bridge.

So, firstly we will calculate the total distance which train had to cover.

→ Total Distance Covered = (Length of train + Length of the train)

→Total Distance Covered = (100 + 500)

→Total Distance Covered = 600 m

$\small{\star{\boxed{\sf{Total \: Distance \: Covered = 600 \: m}}}}$

$\rule{150}{2}$

Now,

We kbow the formula to calculate the total time taken.

$\large{\implies{\boxed{\boxed{\sf{Time \: Taken = \dfrac{Distance \: travelled}{Speed}}}}}}$

★ Putting Values ★

$\sf{\dashrightarrow Time = \dfrac{60\cancel{0}}{\cancel{10}}} \\ \\ \sf{Time = 60} \\ \\ \Large{\implies{\boxed{\boxed{\sf{Time \: Taken = 60 \: s}}}}}$

$\therefore$ Time taken by the train to cross the bridge is 60 seconds.
