Question

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

Answer 1

Let the distance travelled by the truck in $5$ hours be $xkm.$

We know, $1$ hour $=60$ minutes

$\therefore 5$ hours $=(5\times 60)$ minutes $=300$ minutes

The given information in the form of a table is as follows:

$\begin{array}{ccc}\text{Distance travelled(in km)}& 14& x\\ \text{Time(in minutes)}& 25& 300\end{array}$

The distance travelled by truck and the time taken by the truck is directly proportional to each other. Therefore,

$\frac{14}{25}=\frac{x}{300}$

$\Rightarrow x=\frac{14\times 300}{25}=168$

Hence, the distance travelled by truck is $168km.$
