Question 12
a) A boat goes 40 km upstream in 8 hours and a distance of 49 km downstream in 7 hours. Find the speed of the boat in still water.
b) If Nannie can swim downstream at 6 km/h and upstream at 2 km/h. What is his speed in still water?
For each part assume constant still-water speed and a steady current of the same magnitude in both directions.
Answer entry: Enter the integer speeds in km/h for (a);(b), separated by one semicolon, without spaces or units.
