From the perspective of Team Platform, Team Train is moving at a speed $v=\frac{5}{13}c$. Both teams claim that their own set of clocks are properly synchronized, but Team Platform notes that the readings of the two clocks on Team Train differ by 12 nanoseconds. How fat apart, according to Team Platform, are these clocks? (Use the approximation $c=1$ foot/nanosecond, and express your answer in feet.)

From the perspective of Team Platform, Team Train is moving at a speed $v=\frac{15}{17}c$. Both teams claim that their own set of clocks are properly synchronized, but Team Train notes that two clocks on Team Platform, which it measures to be 8 feet apart, are not in sync. By how much does Team Train say they differ? (Use the approximation, $c=1 \,\textrm{foot}/\textrm{nanosecond}$, and express your answer in nanoseconds.)
