Q 10. A loaded truck travels 14 km in 25 minutes. If the speed remains the same, how far can it travel in 5 hours?
If the speed of the truck remains the same, then we can say that the distance travelled by the truck is directly proportional to the time.
After taking 5 hours the truck will travel a distance of let say 'x';
Hence we obtain the relation:
;
thus the truck would travel a distance of 168km in 5 hours.
