Ok first of all we have to convert in km/hr=Speed
So 30min are 0.5hours
Then we use S= distance/time = 5km/0.5 hrs = 10km/hr —> Jill speed
Then S= d/t = 10km/0.5hrs = 20km/hr —> Scott speed
So Scott rode faster
Increase in height can cause climber's gravitational potential energy greater than any other mean
Hope this helps!
