Question

A movie is 2.5 hours long if this duration is multplied by the conversation factor 1 day / 24 hours how will the length of the movie be expressed

Answer 1

    24 hours are ------ 1 day
 
      1 hour is  --------  x day
----------------------------------

thus x day is $\frac{1hour \cdot 1day}{24hours}= \frac{1}{24} day$


so

1 hour is 1/24  day

thus 2.5 hours are  $2.5 \cdot \frac{1}{24}days= \frac{2.5}{24}days= \frac{25}{240}days$


Answer: $\frac{25}{240}$ days, which is approximately 0.1 days
