walking speed is 1/4 my running speed.
let w = the walking speed
then
4w = the running speed
:
I run for 3 minutes and walk for 5 minutes and travel 1700 meters.
write a distance equation; dist = speed * time
we will find the speed in meters/min
:
walk dist + run dist = 1700 meters
5w + 3(4w) = 1700
5w + 12w = 1700
17w = 1700
w = 100 m/sec is my walking speed?
:
:
Check this by finding the distances
5(100) = 500 m
3(400) = 1200 m
-----------------
total: 1700 m
