please can anyone answer this question i will mark you as a brainliest and fillow you​

Answer 1

Answer:

1km/h=5/18m/sec

90*5/18=25

25m/sec

Answer 2

You then divide 90 km/h by this figure(you want to eliminate the “hour” bit) and you get 1/2 km. Hence. V=20km/hr….. covert to m/s gives by converting km to m an d hrs to seconds (20×1000)/3600 = 5.56m/s.
