Question

Ritu walks $1\frac{2}{3}km$ and Hiren walks $2\frac{1}{3}km$. Find the total distance covered by them.

• A. $3km$
• B. $4\frac{1}{3}km$
• C. $4km$
• D. $2\frac{1}{3}km$

Answer 1

The correct option is C $4km$

Distance covered by Ritu $=1\frac{2}{3}km$

Distance covered by Hiren $=2\frac{1}{3}km$

Total distance $=1\frac{2}{3}+2\frac{1}{3}$

$1\frac{2}{3}=\frac{1\times 3+2}{3}=\frac{5}{3}$ and

$2\frac{1}{3}=\frac{2\times 3+1}{3}=\frac{7}{3}$

Thus, $1\frac{2}{3}+2\frac{1}{3}$ $=$ $\frac{5}{3}+\frac{7}{3}$

$=$ $\frac{5+7}{3}$

$=\frac{12}{3}$

$=4km$
