Answer:
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

Explanation:
Speed of car in first 5 minutes = 40 km/h
Distance covered = speed × Time taken
60 minutes = 1 hour
5 minutes = 5/60 hours
Distance covered = 240× 5/60
=20km
Speed of car in next 5 minutes = 60 km/h
Distance covered = 60× 5/60
=5km
∴ Total distance covered = (5+20)km = 25 km
