Question

a car travels a distance of 360km in 5 hour 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

D=360km
T=5h
S=?

S*T=D
S=D/T
S=360/5
S=72 KM/H
IN M/S :
72 *5/18
= 20 m/s
