Answer:
Let speed at walking be X km/h
speed while cycling be y km/h
2x +y =24
x+2y= 39
solving, we get
x = 3 km/h
y = 18 km/h
Now , 1.5x+1.5y= 4.5+ 27 ie. 31.5 km Ans

the speed ratio = 2x+x=24
3x=24
x=24/3
x=8 km
so , he walked 16 kms and cycled 8 kms
in the second part,
the speed ratio = 2x+x=39
3x=39
x=39/3
x=13 kms
he walked 13 kms and cycled 26 kms
