Open in App

Solution

Let x % of 1 day be 1 min.
Then, $\frac{x}{100} \times 1 d a y = 1 m i n [∵ 1 d a y = 24 h a n d 1 h = 60 m i n] \Rightarrow \frac{x}{100} \times 24 h = 1 m i n \Rightarrow \frac{x}{100} \times 1440 m i n = 1 m i n \Rightarrow x = \frac{100}{1440} = \frac{10}{144} ∴ x = 0.069 %$
Hence, 0.069% of 1 day is 1 min.
