Answer 2

Step-by-step explanation:

let s be usual walking speed

then

5/6 s =slower speed

let t be usual time to walk to school

then

(t+4)=time required when walking slower

distance equation

t s= (t+4)(5/6 s)

multiply 6 both the sides

6ts=5s (t+4)

6ts=5ts + 20s

6ts-5ts=20s

t s=20s

divide for sides by s

results

t=20min
