Answer 1

Answer:

1)30 m/sec,108 km/hr

2)720 km/hr,200 m/sec

Step-by-step explanation:

1)Distance = 9000 m & Time = 5 mins

 5mins=5*60 secs

           =300 sec

Speed=9000/300

          =30 m/sec

30*18/5=108 km/hr

2) Distance =2400 km & Time = 3 hours 20 mins

  time=3+20/60

        =3+1/3

       =10/3 hrs

   Speed=2400/(10/3)

              =720 km/hr

  720*5/18=200 m/sec
