Question

A man covers a distance of 15km in 3 hours partly by walking and partly by riding if he walks at 3km per hour and rides at 9km per hour then find the distance he covered by riding

Answer 1

let the time at walking be x
so time during riding =3-x
now from question
3x+9(3-x)=15
3x+27-9x=15
-6x=-12
6x=12
x=12/6=2
so time at walking =2hour
and time at riding=3-2=1hour Answer
