1. Ren decides to test his swimming strength. He starts swimming across a river. He swims with a velocity of 3.5 mi/h north. The river is 0.61 mi wide and carries an eastward current of 1.25 mi/h. How far downstream is he when he reaches the opposite shore?

2. Ashley, Andy, and Abby want to catch gold from an enclosed fortress. However the walls are made of reinforced concrete. They decide to slingshot their friend Ryan over the wall, where they position the slingshot 20 m away from the 6 m high wall. If Ryan is hurtled at 23 m/s at an angle of 40 degrees with the horizontal, does he make it?
