You are a scientist.

You have worked on the Voyager 1 project for a number of years. You receive a satellite phone call while on a team building exercise with your fellow scientists that there is an emergency with Voyager 1. You must escape hostile territory while being pursued by an enemy who wants you for your scientific prowess. You come to a river that is fast flowing, and the only safe landing point on the opposite bank is directly across from an abandoned but functional boat. The width of the river is 1.8 km. The boat has a constant speed of 21 knots. However, the boat’s rudder has been damaged and so the boat cannot be redirected once it has started moving. With you, you have a remote controlled boat which travels at a constant speed, but you do not know what that speed is. You also have a stop watch. You must predict the proper direction to point the boat in order to land on the opposite bank at the landing point.

Your team reached a clearing and has been airlifted out of hostile territory and transported to ground control for Voyager 1. An asteroid has been identified whose movement may put it on a collision course with the satellite. NASA has tasked your team with creating an accurate visual simulation of the motion of the asteroid and satellite relative to ground control and to produce a graph of the separation distance of Voyager and asteroid as a function of time. Voyager's probes can provide information about the asteroid. We need your help to ensure Voyager’s 36 year mission does not come to an end.
