Question

Tanuj walked $8.62km$ on Monday, $7.05km$ on Tuesday and some distance on Wednesday. If he walked $21.01km$ in three days, how much distance did he walk on Wednesday?

Answer 1

Distance travelled on Monday $=8.62km$
Distance travelled on Tuesday $=7.05km$
Suppose the distance travelled on Wednesday $=x$
Total distance travelled in three days $=$ Distance travelled on (Monday $+$ Tuesday $+$ Wednesday)

$\Rightarrow 8.62km+7.05km+x=21.01km$

$\Rightarrow 15.67km+x=21.01km$

$\Rightarrow x=21.01km-15.67km$

$\Rightarrow x=5.34km$
Therefore, Tanuj walked $5.34km$ on Wednesday.
