Question

X takes 3 hours more than Y to walk 30 km. But, if X doubles his pace, he is ahead of Y by 1.5
hours. Find their speed of walking

Answer 1

Answer:

Sy=5      Sx=10/3

Step-by-step explanation:

First remember the Speed formula: $\frac{x}{t}=S$

so if we write it in this way:   t=x/s

it would be easier to solve this question.

given : tx-ty=3

thus: $\frac{30}{Sx}-\frac{30}{Sy}$=3

also given: $\frac{30}{Sy}-\frac{30}{2Sx}=1.5$

Now solve this system of linear equations and you will get Sx and Sy
