Brandon is on one side of a river that is 60 m60 m wide and wants to reach a point 300 m300 m downstream on the opposite side as quickly as possible by swimming diagonally across the river and then running the rest of the way. Find the minimum amount of time if Brandon can swim at 2 m/s2 m/s and run at 4 m/s.

A drowsy cat is looking at a window from across the room, and sees a flowerpot that sail first up and then down past the window. The pot is in view for a total of 0.54 s, and the top-to-bottom height of the window is 1.86 m. How high above the window top does the flowerpot go?
A swimmer is capable of swimming 0.58m/s in still water. She wants to arrive at a point directly across the stream of a 54 m wide river whose current is 0.50m/s. At what angle upstream must she aim? How long will it take her to cross the river?
You want to swim straight across a river that is 76m wide. You find that you can do this if you swim at an angle of θ= 28° from the upstream direction at a constant rate of 1.5 m/s relative to the water. At what rate does the river flow? The angle θ is measured from the river bank (directly upstream is θ=0 while directly across the river is θ= 90)
An athlete crosses a 28 meters wide river by swimming perpendicular to the water current at a speed of 1.1 m/s relative to the water. He reaches the opposite side at a distance of 42 meters downstream from his starting point. w = 28md = 42m vs = 1.1m/s How fast is the water in the river flowing with respect to the ground in m/s?
A student is walking with a constant speed of ??1meters per second along High Street and sees a puddle ??1 meters ahead of her. A bus driver is driving parallel to the student along High Street as well. At the moment the bus is ??2meters behind the student, the bus driver decides he wants to splash he student with water by driving over the puddle as the student walks past. Determine the expression for the speed that the bus must have in terms of the given variables such that the bus and the student reach the puddle at the same time to splash the student.
