The answer is that the 4/10 can is less than 1/2. To find this, just divide each of the fractions to see which is less than 1/2.
1/2 = 0.5
4/10 = 0.4
5/8 = 0.625
0.4 < 0.5
0.625 > 0.5 <—- Wrong!
108 miles 3 hours = 36 mph upstream
108 miles 2 hours = 54 mph downstream
bv = boat velocity in still water
cv = current velocity
bv -cv = 36
bv +cv = 54 Adding both equations
2*bv = 90
boat velocity in still water = 45 mph
since bv + cv = 54
then we know the current velocity = 9 mph
