I need help with these maths questions please.?

Question

these are the question:

2. On average, Anne takes 50 minutes to complete one homework sheet, and has four to do each week. How long does she spend on her homework over 15 weeks to the nearest hour?

3. A worker usually earns between $1030 and $1170 a week. how much money do 15 workers earn in 4 weeks?

that all and can you please give me the explanations as well as the answer.

Answer 1

Item 2.

Per week , Anne spends 50 min * 4 = 200 minutes

For 15 weeks, it is 200 * 15 = 3000 minutes

Now divide 3000 by 60 to get the number of hours = 50 hours

Item 3

Same reasoning as 2 . Answer is between $61800 to $70200  

Answer 2

2.) 4 homeworks/week multiplied by 15 = 60 homeworks total.

     60 homeworks multiplied by 50 minutes = 3000 minutes or 50 hours or

                               2.08 days

3.) the problem here is vague.. so i just took the average from 1030 to 1170.

     1100 (average salary) multiplied by 15 workers multiplied by 4 weeks

     = $66000

Answer 3

The first question. Multiply the 50 minutes by the 4 to be done each wee, then by the 15 weeks.

the second question multiply both the $1030 and $1170 by the 15 workers and then by the 4 weeks. This will give you a range of low to high totals.
