Ryan time = t
Gabriella time = t-3 = 2 hours so t = 5
Ryan speed = s
Gabriella speed = s+42
same distance
distance = speed * time
s t = (s+42)(t-3)
s(5) = (s+42)(2)
3 s = 84
s = 84/3 = 28 km/hr
Ryan Left The science Museum and drove south Gabriella left three hours later driving 42 km/h faster in an effort to catch up to him . after two hours Gabriella finally caught up find ryans average speed

where the heck do you get the 3 from though? I officially got 16.8 as the result because I left the 5 with the s and had something like this. 5s=84. the divided 5 by both sides you know how it do. Then I got s=16.5. So all I have to ask is what happened to the original plot in the movie??
Nevermind I git it cause imma G
