Question

a car travels at a distance of 360km in 5hrs.what is the speed in m/s

Answer 1

Given,
Distance = 360 km 
Time = 5 hr
Speed = ???

We know,
Speed = distance/time
           = 360/5
           = 72 km/hr

Now, convert in m/s:
1km = 1000m 
1 hour = 3600 seconds 

Then,
72 km/hr 
= 72000 m/3600 s 
= 20 m/s

Answer 2

Hi !


Distance = s = 360 km
Time = t = 5 hours


Speed = distance/time
= 360/5
= 72 km/hr


To convert km/hr to m/s , multiply it by 5/18

72 x 5/18 = 20 m/s

Speed = 20 m/s
