Mandarinka [93]

Answer: 0.57 hours each day or 34.28 minutes each day.

Step-by-step explanation:

1. You know that:

-Alejandra worked on the animal report for school for 4 hours in a week.

- A week has seven days.

2. Therefore, to calculate the number of hours she worked on the project each day (which you can call x), you can divide the number of hours  worked on in a week by 7 days.

3. Therefore, you obtain the following result:

x=\frac{4hours}{7day}\\x=0.57\ hours/day

Multiply the result by 60 to obtain the time in minutes, then:

x=34.28\ minutes
