Step-by-step explanation:
So, to find the number of seats already replaced:
5 x 236 = 1180
1 x 348 = 348
1190 + 348 = 1528
So 1528 seats have been replaced.
3000 - 1528 = 1472
And 1472 seats still need to be replaced.

Speed of the boat = u
speed of the current = v
in downstream,
u - v = 105/5
u - v = 21
in upstream
u + v = 105/7
u + v = 15
add both equations
2u = 36
u = 18
v = -3
so
speed of the boat = 18 km/h
speed of the current = 3 km/h
