Question 95927
Suppose you are walking along the side of train tracks at 2 mph. A train is
 traveling 20 mph in the same direction requires 1 minute to pass you. How long
 is the train?
:
Distance you travel, going 2 mph, in 1 minute, (in feet)
{{{((2*5280))/60}}} = 176 ft
:
Distance train travels, in 1 min, going 10 time as fast = 1760 ft
:
Train length: 1760 - 176 = 1584 ft is the train's length
:
Check solution using relative speed between you and the train:
That would be 18 mph
{{{((18*5280))/60}}} = 1584 ft  also
