Question

Ava ran $11\text{km}$ in $100\text{minutes}$ at same speed. Find out the distance he ran in $10\text{minutes}.$

• A. $\frac{11}{10}\text{km}.$
• B. $\frac{10}{11}\text{km}$
• C. $1.1\text{km}$
• D. $11\text{km}$

Answer 1

Answer: (A), (C)

$1.1\text{km}$

In $100\text{minutes},$ Eva ran $11\text{km}.$

$\therefore$ In $10\text{minutes},$ Eva ran $\frac{11}{100}\times 10\text{km}=\frac{11}{10}\text{km}.$

We need to perform $\frac{11.0}{10}.$
Here, $10$ is present in the denominator, so the decimal point needs to be shifted leftwards by one place.

$\frac{11.0}{10}=\frac{1.10}{1}=1.1$

$\therefore$ Eva ran $1.1\text{km}$ in $10\text{minutes}.$
