Answer:
Given speed =35 km /hr. Time =12 minutes =12/60 hours =1/5 hr. Distance =7 km.
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
