Question 280092
There are {{{5280}}} ft in a mile
You will hear {{{5280/30 = 176}}} clicks/mile
If the train's speed was {{{1}}} mile/min, that is {{{60}}} miles/hr
So, {{{176}}} clicks/min means the train's speed is {{{60}}} miles/hr
Therefore, {{{60/176 = 15/44}}} x clicks/min gives the train's
speed in miles/hr
