1. ### Boat travels 48 miles down in 3 hrs n returns up in 12 hrs. What's the rate of stream .?

Boat speed = b. Stream current speed = c. since speed = distance /time, b+c = 48 miles/3 hours = 16, b- c... = 4. Subtracting the second from first eliminates ' b ' to leave 2c = 12. c = 6 miles / hour = Stream current
