Boat speed = 48 mph
current speed = x mph
speed against current 48 - x
speed with current 48 + x
Distance against current 132 miles
Distance with current 156 miles
t=d/r time against = time with current -
132 / ( 48 - x )= 156 / ( 48 + x )
132 ( 48 + x )= 156 ( 48 -x )
6336 + 132 x = 7488 - -156 x
156 x 132 x 7488 + -6336
288 x = 1152
/ 288
x = 4 mph current speed
