Question

a journey of 800 km is done in a total of 10 hours, if 320 km is travel by train and remaining by bus. the same journey is done in 8 hours if 240 km is travel by train and remaining is done by bus. find the ratio of the speed of train to bus.

Answer 1

Let speed of train be x and speed of bus be y.

We are given that a journey of 800 km is done in a total of 10 hours, if 320 km is traveled by train and remaining by bus. Using this, we can set up an equation:

$\frac{320}{x}+\frac{480}{y}=10$

Similarly, we are given that the same journey is done in 8 hours if 240 km is travel by train and remaining is done by bus. Therefore, we can write another equation:

$\frac{240}{x}+\frac{560}{y}=8$

Upon solving these two equations, we get:

$x=\frac{400}{11},y=400$

Therefore, the required ratio is :

$\frac{x}{y}=\frac{1}{11}$
