Answer:
15. Answer = 15 meter per second
16. Answer = Ankur drives faster .
17. Answer = At 2:27 pm motorist reached his destination .
Step-by-step explanation:
- 15 . Answer = Speed = Distance / Time
Speed = 216 / 4 = 54 km/hour
Speed in meter per second = 5/18 * 54 = 15 meter per second
- 16. Answer = Speed of Shyam car = 32 km/hour
Speed of Ankur car = 36 km/hour
So , Ankur drives faster.
- 17. Answer = Speed of motorist = 60 km/hour
Total distance = 150 km
Total time taken to reach 150 km = 150/60 = 2.5 hours = 2 hours 12 minutes
He left at 11:30 am and stopped for 45 minutes so time = 12:15 pm
Time taken by him to reach destination = 12:15 + 2 hours 12 minutes
So at 2:27 pm he reached his destination .
