Question

answer both questions ​

Answer 1

2. Distance: 1000km and 400m    (1km = 1000m)

                    400m= 0.4km    Total = 1000+0.4 = 1000.4km

   Time: 15.5 hrs and 30 mins = 16 hrs

Speed = d/t

           =1000.4/16 = 62.525km/hr

3. Distance: 200km and 100m

                    100m = 0.1km    Total = 200.1km

Speed= 50 2/5 km/hr

Time = d/s

         =200.1/(50 2/5) =3.9 hr
