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 travelled by the truck in 5 hours be x km. 
We know, 1 hour = 60 minutes 
∴ 5 hours = (5 × 60) minutes 
= 300 minutes 
The given information in the form of a table is as follows.
 
 

Distance travelled (in km)	14	x
Time (in min)	25	300

The distance travelled by the truck and the time taken by the truck are directly proportional to each other. Therefore,
\(\frac{14}{25}=\frac{x}{300}\)
\(x=\frac{14\times300}{25}=168\)
Hence, the distance covered by the truck in 5 hours is 168 km.
