Answer 1

Answer:

Step-by-step explanation:half of the journey = 120×1/2=60km

Time=3/5 of total time=3/5×15 hours =9 hours remaining time=15-9=6 hours and distance to be covered =120-60=60 km speed=distance/time=60/6=10km/h hence,speed to cover the remaining time=10km/h

Answer 2

Answer:

Step-by-step explanation:

given: distance bullock has to cover =120km

            time=15hrs

when d=120/2=   60kms

     then time is 3/5*15=9hrs

after 60kms in 9hrs ,then left distance= 60kms

left time =15-9=6hrs

therefore,speed= distance / time

                          =60kms/6hrs=10km/hrs   [anwer]
