if the buses' speeds are x and y km/hr, since distance = speed * time
If X is the faster bus, then
2(x+y) = 200
8x = 8y+200
Now finish it off
Two towns P and Q are 200 km apart. Bus X starts from Town P and Bus Y starts from Town Q at the same time. If the two buses travel towards each other, they meet after 2 hours. If they travel in the same direction, they cross each other after 8 hours. Find the speed of Bus X.
