At top speed, a motorboat travelled 50 km downstream in the same time as it took to travel 30 km upstream. The top speed of the boat in still water is 30 km/h. If x represents the speed of the current and the situation is modeled by 30 50 30-x 30+x algebraically determine the speed of the current. 1. An express train and a passenger bus leave the same city, at the same time, for a destination 350 km away. The rate of the train is 20 km/h faster than the rate of the bus. The train arrives at its destination 2 hours ahead of the bus. If x represents the speed of the bus and the situation is 350 350 modeled by = 2 , algebraically determine the speed the speed of the bus and the X * + 20 train
