Question

Salman traveled to his friend Trump's house, located 19/3 Km away. Salman first walked a distance of 7/4 Km and then traveled some distance by train. Finally, he walked another 4/3 Km to reach Trump's house. How far did Salman travel by train?

Answer 1

Answer:

39/12 km

Step-by-step explanation:

Total distance covered by salman=19/3 km

Total distance traveled by walking=7/4+4/3

=21+16/12     (LCM=12)

=37/12 km

Distance traveled by train= 19/3-37/12

=76-37/12    (LCM=12)

=39/12 km

I hope this helps...... :)

Answer 2

Salman traveled by train is $3\dfrac{1}{4}\ km$

Step-by-step explanation:

Since we have given that

Distance covered = $\dfrac{19}{3}\ km$

Distance covered walk = $\dfrac{7}{4}\ km$

Distance covered train = $x$

Distance covered walked = $\dfrac{4}{3}\ km$

According to question,

$\dfrac{7}{4}+x+\dfrac{4}{3}=\dfrac{19}{3}\\\\\dfrac{21+16}{12}+x=\dfrac{19}13}\\\\\dfrac{37}{12}+x=\dfrac{19}{3}\\\\x=\dfrac{19}{3}-\dfrac{37}{12}\\\\x=\dfrac{228-111}{36}\\\\x=\dfrac{117}{36}\\\\x=3\dfrac{9}{36}\\\\x=3\dfrac{1}{4}$

Hence, Salman traveled by train is $3\dfrac{1}{4}\ km$
