Exercise $18\mathrm{.}12.[$S$][$Section $1\mathrm{.}2][$Goal $1\mathrm{.}1][$Goal $1\mathrm{.}8]$ Millions jam street$-$level crime map website.

In early $2011,$ the British government introduced a crime$-$mapping website that allows people to see crimes reported by entering a street name. The launch of the site, however, was problematic. The BBC reported that the website was jammed by up to five million hits per hour, about $75$ thousand a minute. $[$R$15]$

$($a$)$ Are the figures "five million an hour" and $"75,000$ a minute" consistent?

$($b$)$ Estimate the fraction of the population of London trying to look at that website. Does your answer make sense?
