Question

swapnil reaches his school in 23/60 hours by his school bus. if he walks to school it takes him 31/48 hours. how much more time does it take him to walk to school than go by bus?​

Answer 1

Step-by-step explanation:

A boy goes to his school from his house at a speed of 3 km/hr and returns at a speed of 2 km/hr. If he takes 5 hours in going and coming, the distance between his house and school is:

[A]6.5 km

[B]5.5 km

[C]5 km

[D]6 km

6 km

Let the required distance be x km.

Then,

\frac{x}{3}+\frac{x}{2} = 5

=> \frac{2x+3x}{6} = 5

=> 5x = 6 \times 5

\therefore x = \frac{6\times 5}{5} = 6 km.

Hence option [D] is the right answer.
