Question

The distance between the school and Sanya's house is '$428\mathrm{m}$'. Every day she cycles both ways between school and home. Find the total distance covered in fifteen working days.

Answer 1

$\Rightarrow$The distance between school and home is '$428\mathrm{m}$'.

$\therefore$ Distance covered both ways between school and home each day$=2\times 428\mathrm{m}$

$=856\mathrm{m}$

$\therefore$ Distance covered both ways between school and home in fifteen days$=15\times 856\mathrm{m}$

$=12840\mathrm{m}$

We know that, $1\mathrm{kilometres}\left(\mathrm{Km}\right)=1000\mathrm{metres}\left(\mathrm{m}\right)$

$\therefore$ Distance covered in $\mathrm{kilometres}\left(\mathrm{Km}\right)$$=12840÷1000$

$=12.84\mathrm{Km}$

Therefore, the distance covered in fifteen days is $12.84\mathrm{Km}$
