Question

a train 210 M long to 12 seconds to pass in 1910 long tunnel find the speed of the train

Answer 1

Total distance = Length of train + length of tunnel
=> 210 + 1910
= 2120 metre

We know that
Speed = Distance/Time

Here Distance = 2120
Time = 12

Hence, speed = 2120/12
= 176.67 m/s
or in fraction,
$176 \frac{8}{12} \\ = 176 \frac{2}{3}$
Hope it helps dear friend ☺️✌️
