___________________speed___________time___________distance
bus________________r_______________3_______________(r)(3)
bus________________r+10____________3_______________(r+10)(3)
Total______________________________________________810

%283r%2B3r%2B30%29=810

6r%2B30=810
r%2B5=810%2F5
r=810%2F5-5
r=162-5
r=177 and faster bus was 187
