<PRE><B>Question 933269</B>
If Ram walks at 5 kmph to his school then he reaches 5 minutes early and if he walks at 4 kmph he reaches 5 minutes late . what is the actual distance Ram&#39;s house and his school?

let distance be x
Let his original speed be y to reach in time

5 minutes = 5/60 hours = 1/12 hours

Normal time = x/y

x/y -x/5 = 1/12

x/4 -x/y = 1/12

add the two equations

x/4 -x/5 = 1/6

x/20 = 1/6

6x=20
x= 10/3

distance = 3.33 km
