A train travels 20% faster than a car. Both start from point A at the same time and reach point B, 180 km away at the same time. On the way the train takes 30 minutes for stopping at the stations. What is the speed (in km /hr) of the train?

Solution:

Let the speed of the car = x km /h
The speed of the train

=x×120/100×{6x}/5

km /h
According to the question.
Time

=\Distance/\Speed⇒t=180/x

⇒

t-30/60={180×5}/{6x}

⇒

180/x-{180×5}/{6x}=1/2

⇒

180/{6x}=1/2

∴ x =60 km /h
Hence, speed of train

60×6/5=72

km /h
