Question 1078879
X===================================Y
from Y, distance is 100x, where x is number of hours
from X, distance is 150(x-1/2)
The distances add to 600 km
100x+150x-75=600km
250x=675 km
x=2.7 hours or 2h42m or 11:42 am
That would be 270 km towards X from Y
and
150*2.2=330 km towards Y from X
