​

Answer 1

Answer:

Speed of car in first 15 minutes = 40 km/h

Distance covered = speed × Time taken

60 minutes = 1 hour

15 minutes =

60

15

hour

Distance covered = 240×

60

15

=10km

Speed of car in next 15 minutes = 60 km/h

Distance covered = 60×

60

15

=15km

∴ Total distance covered = (10+15)km = 25 km

∴ 25 km is correct

Answer 2

Answer:

Answer is 0.8 km.

Or , 0.8 x 1000 meter =800 meter

Using formula,

Distance =speed x time.

Here speed is 48km/h.

To solve any question ,we should have to look at units.

Here time is given is minutes

So first we convert it into hour .

Using given approach we can easily convert unit in form to another...

60 minutes =1 Hour ,

1 minute =1/60 hour,

So , distance =speed x time.

Distance =(48km/h) x (1/60)

Distance = 0.8 km.( 800m)
