Hello,
i have problem with map scale here, what does it mean when stated there on the map 'approx scale 1:7500 or 1:15000'
does it mean 1cm on the map = 7500cm/ 75m/ 0.075km

& normally how long does normal average person take for 1km distance with walking?

FireIce SG

normal stroll, for male....every stride is i think..... 50cm per second....?
assuming straight road with no traffic lights or obstacles and walking at constant pace

so it'll end up ard 1.8km/hr
d route i planned is ard 20km, it'll take me roughly half day to complete then
really thanks, d response was fast - u don't stay in front of d forum all d time right? Mr. Green

from my experience in the army

1km will take about 10~15 mins depending on walking speed

all in cm...

so 1 : 75000 means 1 cm on the map represents 75000 cm on the actual ground; which equivalents to 750m and .75 km.

Good luck for the walk
