Question

Answer 1

Answer:

18.33km

Step-by-step explanation:

Speed in first 10min= 50km/hr

Distance covered in first 10min= (1/6x50)km= 8.33km  {as 10min as a part of an hour=10/60 or 1/6}

Speed in next 10min= 60km/hr

Distance covered in this period= (1/6x60)km= 10km

now,

        Total distance covered= (8.33+10)km= 18.33km
