While Moving from A to B i.e. ( while running )

V = 5 m/s
T = 100 s
S = ?
let the distance be X.

Formula of distance Distance = Speed×Time

S = V×T
S = 5×100
S = 500m

While moving from B to C i.e. (while walking )

V = 1 m/s
T = 100s
S = ?

Let the distance be X.

Formula of distance Distance = Speed×Time

S = V×T
S = 1×100
S = 100m

Formula of Average Speed 》》

$\frac{Total\:distance}{Total\:time}$

$\frac{500+100}{100+100}$

$\frac{600}{200}$

3 m/s $\boxed{ans}$
