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 .
