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

Let us assume the the distance covered by the car is "x" km.

Case 1)

A car moves with a speed of 40km/h for 15 minutes.

Here; speed = 40 km/hr and time = 15 min = 0.25 hr.

We know that,

Distance = Speed × Time

Substitute the known values,

→ x = 40 × 0.25

→ x = 10 km

So, the distance covered by the car in first half is 10 km.

Case 2)

The car cover next 15 minutes with a speed of 60 km/hr.

Again,

Distance = Speed × Time

→ x = 60 × 0.25

→ x = 15 km

Total distance covered by the car = Distance covered by the car in (first 15 minutes + next 15 minutes)

= (10 + 15) km

= 25 km

Therefore, the total distance covered by the car is 25 km.
