• A. 20 km
• B. 48 km
• C. 40 km
• D. 32 km

Answer 1

$\text{Given, Raju covers 12 km in 3 hours.}$

$\text{Speed}=\frac{\text{Distance}}{\text{time}}$

$\Rightarrow \text{Speed of Raju}=\frac{12km}{3h}=4\text{km/h}$

$\text{Distance covered in 5 hours:}=4km/h\times 5h=20km$

$\text{Distance covered in 10 hours:}=4km/h\times 10h=40km$

$\text{Distance covered in 8 hours:}=4km/h\times 8h=32km$

$\text{Distance covered in 12 hours:}=4km/h\times 12h=48km$
