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 5 min late. What is the actual distance between Ram's house and his school?

Answer 1

Time required at 5kmph= x/5 hr=60x/5 minutes=12x min
Time require at 4kmph= x/4 hrs== 60x/4 minute=15 x min
As per question  12x+5=15x-5
                                 3x=10 ⇒x=3.33 km
The distance of school from Ram's house is 3.33km
