Question

Question 10.
A loaded truck travels 14 km in 25 minutes. If the speed remains the same, how far can it travel in 5 hours?

Answer 1

Let distance covered in 5 hours be x km.
$\because 1hour=60minutes$
$\therefore 5hours=5\times 60=300minutes$

$\begin{array}{ccc}Distance\left(inkm\right)& 14& x\\ Time\left(inminutes\right)& 25& 300\end{array}$

Here distance covered and time taken are in direct proportion.

$\therefore \frac{14}{25}=\frac{x}{300}\Rightarrow x\times 25=14\times 300\Rightarrow x=\frac{14\times 300}{25}=168km$
Hence, the distance covered in 5 hours is 168 km.
