Answer:
1 unit left and 4 units down
To find their mph you would have to divide by 2 to find out how much they got in 1 hour instead of 2. You would have to do 4 2/3 / 2. An easier way to do this is just doing 14/3 x 1/2 which is the same thing except making 4 2/3 a fraction and changing divided by 2 to multiply 1/2. The answer you would get is 14/6, which is 2 1/3 miles per hour. To do this quickly you could just look at the question and divide 4 by 2 to get 2 and then divide 2/3 by 2 to get 1/3 and then add them up.

X- speed of the ship in still water
a- speed of current
(x+a)- speed with current
(x-a) - speed against current
(x+a)*3=72
(x-a)*4=72
x+a=24
<u>+ x-a=18
</u> 2x =42
x = 21
x+a=24, 21+a=24, a=3
The speed of the ship in still water = 21 km/h,
the speed of the current =3 km/h.
