You can put this solution on YOUR website! Town x and town y are 755km apart.
Doreen drove from x to y at 75km per hour.
1 hour later richard drove from y to x at 95km per hour.
At what distance from x did they meet.
:
Find the travel time of each to their meeting point
let t = r's travel time
then
(t+1) = d's travel time
write a dist equation, dist = speed * time
75(t+1) + 95t = 755
75t + 75 + 95t = 755
170t = 755 - 75
t = 680/170
t = 4 hrs is r's travel time
5 hrs = D's travel time from x where they met
Find her dist
5 * 75 = 375 mi from x
