Answer 1

Answer:

Listen As time is equal to distance upon speed so time is equal to 8 hours

Answer 2

Answer:

  First of all

            >> time = distance / speed

we have ,

 >>total speed on which we have to travel  to 10 km = 20 km/hr

 >>total speed on which we have to travel upto remaining distance = 80 km / hr

     

Step-by-step explanation:

 

Total speed = 80 - 20 = 60 km /hr

Total distance = 20 km

 time on speed 80 km/hr =  Total distance / Total speed

                                             = 20 / 60 =>> 0.34 hr

                                             =>> 20.4 min
