Total Time = 195 minutes
Speed = 40 km/hour => \(40\over60 \)minute=\( 4\over6 \)
s = \(d\over t\)
\(4 \over 6\) = \(d \over 195\)
d= \((4 *195) \over 6\)
d= \(780 \over 6\)
d = 130

A15 seconds

C13 seconds

D20 seconds

Answer is : 18 seconds
Total Distance = Train length + bridge distance
                      = 120 metre + 80 metre
                      = 200 metre.

Speed Of Train = 40 km/h
                       \(=\frac{(40*1000)}{(60 *60)} m/s\)

Time To Cross a bridge = \((distance)\over(time)\)

                                     =\(\frac{\frac{200}{ (40*1000)}}{(60 *60)}\)

                                    \(=\frac{(200 * 60 * 60)}{(40 * 1000)}\)
                                     = 18s

A120

B150

C200

D300

Nithin K ? Apr 7 '2018 at 16:2

Answer is : B.) 150

Explanation:

Let the length of the train is x meter and Speed of the train is y meter/second
Then \(\frac{x}{y} = 15\) [because \(\frac{distance}{speed} = time\)] 
\(\implies y = \frac{15}{x}\)

\(\begin{aligned} => \frac{x+100}{25} = \frac{x}{15} \\ x = 150 \text{ meters} \end{aligned}\)

So length of the train is 150 meters
