As I may have to wait 0 minutes or 15 minutes, the average time of waiting will be 71⁄2 minutes.
If I wait x min., and a horse ’bus arrives, I should reach the Bank in 15 mins, if I took it.
If I waited longer for a motor, which, on the average, will now turn up in 71⁄2 - x mins., I should reach the Bank in 171⁄2 - x mins.
If, therefore, x is greater than 21⁄2, the motor is the quicker.

The historical charade—
My first, if foolishly or rashly taken,
May mar the future prospects of your life.
My second, by her fickle lord forsaken
(Sad type of many a gentle, patient wife).
May toil and moil to feed his many babies,
While he goes flirting off with other ladies.
The thrifty monarch of a former age
My whole a place in Britain’s history fills.
Immortalised in Shakespeare’s magic pages
As one who’d fain reform his tailor’s bills!
is solved by Stephen (Step-hen).
