A loaded truck travels 14 km in 25 min. If the speed remains the same,how far can it travel in 5 hrs?
It is easy
Distance=14km (given)
Time=25 min (given)
If, distance =5hrs=300min (given)
then, let time =n
It is a case of direct variation
therefore, 14 =25
n 600
By making cross multiplication
we obtain 14 X 600 =n X 25
24
14 X 600 =n buy dividing 25 by 600
25 we obtain,14 X 24=336
1
Therefore if time taken is 600 minutes the distance cover will=336 km
One important thing do not for got to give me thumbs up.
