d) Ali's friends Bobbi and Charlotte are having a race to a distant planet 30 light years away. Ali is the race official who stays on Earth. Bobbi is in a rocket that can travel at 2/3 c; whereas Charlotte's rocket travels at a speed of 0.8 c. Bobbi and Charlotte start at the same time. Sketch space-diagrams from Ali's perspective. Repeat for both Bobbi's perspective. [Two diagrams total. Graph paper not necessary.] Calculate how long it takes Bobbi and Charlotte to finish the race from each perspective. Show your work. [Note: Assume Bobbi and Charlotte are already at the speeds given when they cross the starting line. Please label all objects and events relevant to the problem.]
