Linda and Albert are measuring the length of a building. Albert stands next to the building and measures its length as 30 units. Linda is in a rocket flying overhead and uses her clock and the speed of the rocket to measure the building. Linda clocks her flyover time as 20 units of time resulting in a length of 24 units. Albert watches Linda and measures her flyover time as 25 units of time. Verify that these pairs of measurements are consistent and determine Linda's speed as a fraction of the speed of light
