4. 1) m soatda; 2) p sekundda; 3) m soat l minut va p sekundda necha minut bor?

1. 1 soat = 60 minut, shuning uchun \(m\) soatda \(60m\) minut bor.

2. 1 minut = 60 sekund, shuning uchun \(p\) sekundda \(\frac{p}{60}\) minut bor.

3. \(m\) soat, \(l\) minut va \(p\) sekunddagi jami minutlar:

   \[60m+l+\frac{p}{60}\]

Javob: 1) \(60m\) minut; 2) \(\frac{p}{60}\) minut; 3) \(60m+l+\frac{p}{60}\) minut.
