A motorboat travels 132 km in 4 hours going upstream. It travels 196 km going downstream in the same amount of time. What is the
rate of the boat in still water and what is the rate of the current?
1 answer:
Answer:
Step-by-step explanation:
x = speed of the boat
y = speed of the current
x + y = 162/3 = 54 mph
x - y = 132/3 = 44 mph
Add the two equations to get
2x = 98
x = 49 mph
y = 54 - x = 54 - 49 = 5 mph or something
