Question

a man walks 10 kilometre then travel A certain distance by train and then by bus as far as twice by the train if the whole journey is of 70 kilometre how far did he travel by train

Answer 1

Answer:

Step-by-step explanation:

Let distance by train be x km,hence by conditions,

10+x+2x=70

X=20

Hence,he travelled 20km by train

Answer 2

$\displaystyle\huge\pink{\underline{\underline{Question}}}$

A man walks 10 kilometre then travel A certain distance by train and then by bus as far as twice by the train if the whole journey is of 70 kilometre how far did he travel by train .

$\displaystyle\huge\green{\underline{\underline{Solution}}}$

${\boxed{\red{Given\: is\: that }}}$

Let the distance travelled by train be x kilometres .

So , therefore According to the statement .

Distance covered by walking = 10 km

Distance covered by train = x km

Distance covered by bus = Twice covered by train i.e 2 × ( x )

= 2 x km

Total distance covered = 70 km

${\boxed{\red{Total\: distance\: covered\:by\:train}}}$

$\hookrightarrow\:10\:+\:x\:+\:2x\:=\:70$

$\hookrightarrow\:3x\:=\:70\:-\:10$

$\hookrightarrow\:3x\:=\:60$

$\hookrightarrow\:x\:=\:\dfrac{60}{3}$

$\hookrightarrow{\boxed{\purple{\:x\:=\:20\: kilometres}}}$

As let in the starting of the question x = distance covered by train .

So therefore the distance covered by train is 20 km .
