Question 1116655
Bryan and Yuan started out at their houses and are biking towards each other.
 Brian started out first, and has already gone 5 miles.
 He bikes at a constant speed of 3 mph. Yuan just left, and rides at 4 mph
 when the boys meet halfway between their houses, they will continue to the park together.
 How long will that take? How far will each boy have ridden? 
:
Since they meet half way, we know they rode the same distance.
let t = the time Yuan rides to meet Bryan
"
write a distance equation, dist = speed * time
B's dist = Y's dist
3t + 5 = 4t
5 = 4t - 3t
5 = t
5 hrs riding by Yuan
5 + {{{5/3}}} = 6{{{2/3}}} hrs or 6 hrs 40 min rode by Bryan
:
Confirm this by finding the distance they rode
5 * 4 = 20 mi by Yuan
6{{{2/3}}} * 3 = 20 mi by Bryan alsol
