Question

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 the distance covered in $5$ hours be $x$ km.

We know that $1$ minutes $=\frac{1}{60}$ hour

Therefore, $25$ minutes $=25\times \frac{1}{60}=\frac{5}{12}$ hour

Speed of loaded truck to cover $14$ km in $\frac{5}{12}$ hours is $\frac{dis\tan ce}{time}=\frac{14}{{\displaystyle \frac{5}{12}}}$ km/h

$=\frac{14}{5}\times 12$ km/h

$=\frac{168}{5}$ km/h

Now, since the speed remains constant.

So, the distance traveled by truck in $5$ hours at $\frac{168}{5}$ km/h is $speed\times time=\frac{168}{5}\times 5$ km

$=168$ km

Hence, if the speed remains the same, the truck can travel $168$km in $5$ hours.
