Question

Sharda can walk $8\frac{1}{3}\text{km}$ in one hour. How much distance will she cover in $2\frac{2}{5}\text{hours}?$

• A. $10\text{km}$
• B. $\frac{25}{6}\text{km}$
• C. $20\text{km}$
• D. $\frac{100}{3}\text{km}$

Answer 1

The correct option is C $20\text{km}$

Given :
Distance covered in one hour
$=8\frac{1}{3}\text{km}=\frac{25}{3}\text{km}$
Given time $=2\frac{2}{5}\text{hours}=\frac{12}{5}\text{hours}$
So, total distance covered in $\frac{12}{5}$ hours
$=\frac{12}{5}\times \frac{25}{3}\text{km}$
$=\frac{12\times 25}{5\times 3}\text{km}=20\text{km}$
