Question

x takes 3 hrs more than y to walk 30 km. but if x doubles his pace, he is ahead of y by 1.5 hrs .find speeds of walking.

Answer 1

distance=30km
let y take M hours to walk
than x take M+3 hours to walk
Speed(x)= 30/M+3
Speed(y)= 30/M
when speed of x= 2(30/M +3)
distance covered by y in 1.5 hour= 1.5×30/s of y
=1.5×30/30/M
=1.5M
distance covered by X= distance covered by y+ 1.5M
