Question

If Ram walks from his house at 5 kmph, he reaches school 5 min early, and if he walks at 4 kmph he reaches it 5 min late. What is the actual distance between Ram's house and his school?​

Answer 1

let the correct time be x and distance=y

y=(x-5)*5

y=5x-5

5x-y=-5

y=(x+5)4

y=4x+20

4x-y=20

solving graphically we get

X=-15

y=-29
