I guess I'm an average speed walker.

d= v .t
> d = 50 km/hr (18 min)
>d = 50 km/60 min (18min)
d= 50 km (18)/60
d =900 km/60
d = 15 km >>the distance travelled

If you walk at an average of 3 miles per hour (approximately 4.8 km/hr) at a distance of 15 km:
t= d/v
=15 km/4.8 km/hr
t = 3.125 hrs or (3 hours and 7.5 minutes)>>the time you need to walk on 15 km at the speed of 4.8 km/hr.♥

If you walk at 4km/h then inversely proportional equation would give you a time of 18*50/4 minutes (approx 200+ minutes)
