Question
A swimmer is capable of swimming 1.00 m/s in still water.
If she aims her body directly across a 150-m-wide river whose current is 0.80 m/s, how far downstream (from a point opposite her starting point) will she land?

Her time to cross will be T = 150/0.8 seconds. During that time, she will drift downstream by 0.80 T meters.
Do the numbers.

I see two similar triangles, her distance downstream as x m
x/.8 = 150/1
x = 120
x/.8 = 150/1
x = 120
