Alice is observing the arrivals and departures at a spaceport. She observes one flight land at pad D7, and then notes another flight take off from pad G23 seventeen seconds later. Alice knows that the distance between pad D7 and pad G23 is 1240 meters in her frame of reference. Meanwhile, Bob flies by the spaceport at a high speed V and observes the same landing and takeoff, though he records a different time and distance between the two events, based on his frame of reference. If both Alice and Bob plug in their values for the elapsed time and distance between the landing and takeoff into the formulas below (where c is the speed of light, t is the elapsed time, and x is the distance), which one will give the same answer for both?

You have been asked by a school to help automate their accounts processing. Every few days they receive a text file from the bank detailing payments received (BPAY sheet). This information must be matched to the system data that has been downloaded into Excel (SYS DATA sheet) and a report produced that will be uploaded to the school system.

Imagine that Bob, at a spaceport, observes Alice flying by to the right in her spaceship at a velocity of 0.9c. When Alice’s ship had been previously docked at the spaceport, Alice had measured its length as 100 meters. Alice has five clocks on her spaceship: one in front (at 0 meters), one at 25 meters, one at 50 meters, one at 75 meters, and one at the rear at 100 meters. All the clocks are synchronized in Alice’s frame of reference. When Alice flies by Bob, Bob uses his lattice of synchronized clocks to take simultaneous photos of Alice’s clocks (simultaneous in Bob’s frame of reference). If Bob’s photos show that Alice’s front clock reads t = 0 at that instant, what equation below would give the time that the clock at 50 meters has in the photos?
