Question 1000287
No way to find a unique answer. Way too little information. We need at least two more pieces of information.


We could not even find a unique answer if the distance between A and B was given as in the problem below:
"One tourist left point A, cycling towards point B, 6 hrs after a second tourist had left point B cycling towards point A. Both tourists reached their destinations at the same time. The distance between points A and B is 200 km".
In that case, we could define variables, translate the information into equations,
and we would still need an extra equation to be able to find a unique answer:
{{{v[1]}}}= average speed of the first tourist, in km per hour.
{{{v[2]}}}= average speed of the second tourist, in km per hour.
{{{t}}}= time the first tourist spent cycling from A to B, in hours.
{{{t+6}}}= time the second tourist spent cycling from B to A, in hours.
{{{t*v[1]=200}}}= distance cycled by the first tourist, in km.
{{{(t+6)*v[2]=200}}}= distance cycled by the second tourist, in km.
Unfortunately, the system of equations {{{system(t*v[1]=200,(t+6)*v[2]=200)}}} ,
with 3 variables related by only 2 equations,
has an infinite number of solutions.
We can tabulate some of them:
{{{matrix(8,4,
t,t+6,v[1]=200/t,v[2]=200/(t+6),
2,8,100,25,
4,10,50,20,
5,11,10,18&2/11,
8,14,25,14&2/7,
10,16,20,12.5,
14,20,14&2/7,10,
16,22,12.5,9&1/11)}}}
Since the possibilities are infinite, I cannot list or describe them all.
