At noon, ship A is 100 kilometers due east of ship B. Ship A is sailing west at 12 kilometers per hour, and ship B is sailing south at 10 kilometers per hour. At what time will the ships be nearest to each other, and what will this distance be? I know that the answer is: t is approximately 4.92, making the time approximately 4:55 PM, and distance is approximately 64km. My teacher has told me to use two formulas, one being the distance formula, but other than that I do not know how to go about the problem. Please help. Thanks!
