Explanation:
Speed of car in first 15 minutes = 40 km/h
Distance covered = speed × Time taken
60 minutes = 1 hour
15 minutes = 6015 hour
Distance covered = 240×6015=10km
Speed of car in next 15 minutes = 60 km/h
Distance covered = 60×6015=15km
∴ Total distance covered = (10+15)km = 25 km
∴ 25 km is correct

Answer:
Total Speed = 20 + 60 = 80 km/h
Total Time = 15 + 15 = 30 minutes or 1/2 hour
Total Distance = Total Speed × Total Time = 80 × 1/2 = 40 km
• The total distance covered by the car is 40 km.
