In 1 km races, runner 1 on track 1 (with time 2 min, 27.95
s) appears to be faster than runner 2 on track 2 (2 min, 28.15 s).
However, length L2 of track 2 might be slightly greater than length
L1 of track 1. How large can L2 - L1 be for us still to conclude that
runner 1 is faster?
[tex]\frac{1000 m}{147.95 s}=\frac{L m}{148.15 s}[/tex]
I get 1.35 the textbook gives an answer 1.4
I would have posted this in the homework section, but things have changed here and I haven't posted for years.
