Question

If a person walks at the rate of 2 km per hour, the distance that he covers in 4 hours is .

• A. 6 km
• B. 4 km
• C. 8 km

Answer 1

The correct option is C 8 km

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

We need to find the distance that the person covers in 4 hours.

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

Therefore, the distance that he covers in 4 hours = 8 km
