Question

A and B are two persons travelling from two towns towards each other along a road at the same time. A travels 6 km more than B every day The number of km travel by AB in each day is twice the number of days before they meet each other. Find the number of kilometers travelled by (Ans: A travels 18 each of them every day.

Answer 1

Answer:

a=b+6

now b+6 +b km is covered each day

total dis x then they will take time t= x/2b+6 days

now

2b+6=2t or t=b+3

x= (b+3)(2b+6) now a=18 then b=12

x= 15×30=450km time = 15 days
