...
rate of current be xmph
..
rate with current = 32+x : d= 228 miles
rate against current = 32-x: d=156 miles
..
times are same, so equate the time
..
228/(32+x)= 156/(32-x)
228x(32-x)=156(32+x)
7296-228x= 4992+156x
reorganise
228x+156x=7296-4992
72x= 2304
/72
x= 2304/72
x= 32 mph the rate of current
