# Easy Time, Speed & Distance Solved QuestionAptitude Discussion

 Q. $X$ and $Y$ start walking towards each other at 10 am at speeds of 3 km/hr and 4 km/hr respectively. They were initially 17.5 km apart. At what time do they meet?
 ✖ A. 2:30 pm ✖ B. 11 :30 pm ✖ C. 1:30 pm ✔ D. 12 :30 pm

Solution:
Option(D) is correct

Let after $T$ hours they meet

Then, $3T+4T = 17.5$

$T = 2.5$

Time = 10:00 am + 2.5 hour = 12:30 pm

Simply we can solve these type of questions ..

Total distance/ total speed(x+y)

17.5/(3+4) = 2.5s
