Answer 2

The time taken reduced by 0.6 minutes.:

Step-by-step explanation:

Since we have given that

Speed = 96 km/hour

Time = 40 minutes

So, Distance covered is given by

$Speed\times time\\\\=96\times \dfrac{40}{60}\\\\=64\ km$

If speed of train is increased by 4 km per hour.

Then, speed becomes 96+4=100 km/hr

So, Time taken by him would be

$\dfrac{64}{100}\\\\=0.64\times 60\\\\=38.4\ minutes$

Hence, the time taken reduced by

40-38.4 = 0.6 minutes.

Therefore, the time taken reduced by 0.6 minutes.
