i hope it will be helpful

Answer:

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

Distance covered = speed × Time taken

60 minutes = 1 hour

15 minutes =   15/60 hour

Distance covered = 240×  60 /15 =10 km

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

Distance covered = 60×  60 /15 =15 km

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

∴ 25 km is correct
