Question

Solve the following word problems.

Amin travelled $2,39,487km$and Naaz travelled$14,56,90,000cm$. How many kilometres did they travel in all $?$

Answer 1

Distance travelled by Amin $=2,39,487km$

Distance travelled by Naaz $=14,56,90,000cm$

Converting $cm$to $km$

So, $$\begin{gathered} 14,56,90,000cm=\frac{14,56,90,000}{1,00,000}km \\ =1,456.9km \end{gathered}$$ $\left[\because 1cm=\frac{1}{1,00,000}km\right]$

Hence distance travelled by Naaz $=1,456.9km$

Total distance travelled by both of them $=2,39,487km+1,456.9km$

$$\begin{gathered} 2,39,487.0km \\ +1,456.9km \\ --------- \\ 2,40,943.9km \end{gathered}$$ $=2,40,943.9km$

Hence, the total distance travelled by both of them is $2,40,943.9km$.
