Answer:
Let:−
\sf{\longrightarrow Distance\: covered\:_{(train)}=x}⟶Distancecovered
(train)
=x
\sf{\longrightarrow Distance\: covered\:_{(bus)}=2x}⟶Distancecovered
(bus)
=2x
\sf\small\underline\blue{Given:-}
Given:−
\sf{\longrightarrow Total\: distance=70km}⟶Totaldistance=70km
\sf{\longrightarrow Distance\: covered\:by\:walk=10km}⟶Distancecoveredbywalk=10km
\sf\small\underline\blue{To\:Find:-}
ToFind:−
\sf{\longrightarrow Distance\: covered\:_{(train)}=?}⟶Distancecovered
(train)
=?
\sf\small\underline\blue{Solution:-}
Solution:−
We solve this question by setting up equation. As given in the question that a man walks 10km then travels a certain distance by train and then by buses far as twice by the train. if the whole journey is of 70km.
\sf\small\underline{Calculation\: begin:-}
Calculationbegin:−
\sf{\longrightarrow Distance\:_{(by\:car+train+walk)}=Total\:_{(distance)}}⟶Distance
(bycar+train+walk)
=Total
(distance)
\rm{\longrightarrow 2x+x+10=70}⟶2x+x+10=70
\rm{\longrightarrow 3x+10=70}⟶3x+10=70
\rm{\longrightarrow 3x=70-10}⟶3x=70−10
\rm{\longrightarrow 3x=60}⟶3x=60
\rm{\longrightarrow x=20}⟶x=20
\sf\large{Hence,}Hence,
\bf{\longrightarrow Distance\: covered\:_{(train)}=20km}⟶Distancecovered
(train)
=20km
