Question

If a person walks at the rate of $2$ km per hour, then the distance covered by him in $4$ hours is ____.

• A. 10 km
• B. 8 km
• C. 6 km
• D. 4 km

Answer 1

The correct option is B 8 km

$2$ km per hour as a ratio is $\frac{2}{1}$ .

We need to find the distance covered in $4$ hours.

$\Rightarrow \frac{2\times 4}{1\times 4}$ = $\frac{8}{4}$

Distance covered in $4$ hours = $8$ km
