Question 1063502
.
lucia travels from point A to point B at 100km/h. Jane leaves at the same time as Lucia, travelling from point B to point A at 50km/h. 
The distance from A to B is 100km.How long after the two leave will they meet on the road?
~~~~~~~~~~~~~~~~~~~~~


<pre>
time = {{{100/(100+50)}}} = {{{100/150}}} = {{{2/3}}} of an hour = 40 minutes.


Initial distance between them is 100 km.


Since they move toward each other, the distance decreases at the rate of 100 km/h + 50 km/h = 100 km/h.


Therefore, time = {{{Distance/Rate}}}, as I did above.
