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.

In 25 min distance travelled =14km

distance travelled in 1 min=14

 25

min in 5hrs=5*60=300min

distance travelled in300min= 14 *300 = 168 km (ans)

In 25 mins  truck travels 14km.

In 1min=14/25

In 300 mins=14/25*300=168km.

Plz like

@nimit its easy but you did not get the ans

we just have to use unitary method to solve this question.........

truck covered 14 km in 25 min so

25 min =14 km

1 min= 14/25km

300min[5x60] = 14/25x300

= 168km

In 25 min distance travelled =14km

distance travelled in 1 min=14

25

min in 5hrs=5*60=300min

distance travelled in300min= 14 *300 = 168 km (ans)

It's quite simple that it's. A direct propostion so that formula - x1/y1 is x2/y2 . So let take x1 as 14 and leave y1 as itself and take x2 as 25 and y2 as 300 because 5 hrs. Is 300 minutes . So by cross multiplying you'll get 14 * 300 and 25*y1 so. 14*300 is 4200 and divide it with 25 4200/25 is 168.

Distance = speed *time

Time = 25mins = 25/60,=5/12hr
Speeds = distance /time
Speed = 14k/5/12hr
=14*12/5
=168/5
Distance in case 2 = 5*168/5
=168 km thus us the final answer
