• A. $24km$
• B. $27km$
• C. $30km$
• D. $36km$

Answer 1

The correct option is B

$27km$

Find distance cover in $6hours$.

A boy walks $18km$in $4hours$,

$\therefore$A boy covers the distances in $1hour$$=\frac{18}{4}=4.5km$

A boy walks $4.5km$in $1hour$

Then distances cover in $6hours=6\times 4.5=27km$

$\therefore$The distances covered $27km$ in $6hours$

Hence, the correct option is B.
