Commercial arithmetic

A boy walks 88 paces in a minute. If his average pace length is $0.55\text{ m}$ , what fraction of an hour will it take him to walk $1936\text{ m}$ ?

Worked solution (try it first)

Each minute he walks 88 paces of 0.55 m: $88 \times 0.55 = 48.4$ m a minute.
Time is distance over speed: $1936 \div 48.4 = 40$ minutes.
As a fraction of an hour: $\frac{40}{60} = \frac23$ , option D.
