rajiv walks and cycles at uniform speeds. when he walks for 2hrs and cycles for 1hr, distance travelled is 24 km. when he walks for ihr and cycles for 2 hrs the distance travelled is 39 km. find his speed of walking and cycling. if he walked and cycled for equal time in 3hrs how much distance doees he cover?

let his walking speed be x km/hr

cycling speed = y km/hr

d = s*t

for walking d = 2*x for cycling = d = y

case 1

24 = 2*x +y

2x +y = 24 .....1

case 2

39 = x +2y........2

solving 1 and 2

x = 3 km/hr y = 18 km/hr

in 3 hrs

d = 3 *1.5 +18 *1.5

d =4.5 + 27

d = 31.5  kms
