please answer​

Answer 1

Answer:

i)45km/hr

ii)1.25m/s

Explanation:

1 hr = 60 min

20 min = 20/60 hr.

∴Speed = Distance / Time

              = 15 / 20/60

               =45km/hr

1min= 60sec

20min=1200sec.

1km=1000m

15km=15000m.

∴Speed= 15000/12000

            =1.25m/s

Answer 2

Answer:

speed =distance /time so 15/20÷60 =45km and 15×1000/20×60=12.5 ms

45km/hrs and 12.5ms
