Question

a loaded truck Travels 14 kilometres in 25 minutes. if the speed remains the same, how far can it travels in 5 hours

Answer 1

if it travels 14 KM's in 25 minutes then it travels
$(14 \div 25)$
km in 1 minute
it means that it travels
$(14 \div 25) \times 300$
kilometres in 5 hours
$= 14 \times 12$
kilometres in 5hrs
= 168 kms

Answer 2

 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
