Your answer is correct. Indeed:
- In order to find the degrees per minute, you have to divide the full rotation angle (which is 360deg) by the number of minutes (which is 60):
360deg ÷ 60min = 6 deg/min
- In order to find how many minutes have passed, you subtract the times:
1h50m - 1h25m = 0h25m
- You then find how many degrees correspond to 25minutes:
6 deg/min × 25 min = 150deg
- Lastly, you transform degrees into radiants, through the proportion:
deg : 180 = rad : π
Therefore,
150 : 180 = rad : π
rad = (150×π)/180 = 5π/6
You need a table with the content of sodium per serving.
This is the table:
butter 1 pat 41mg
coffe 250 ml 0
eggs 1 serving 60mg
toast 1 slice 170mg
orange
juice 250 ml 4 mg
With that table you can calculate the content of sodium in the breakfast, this way:
<span>orange juice: 1 * 41 mg = 4 mg
2 eggs: 2*60mg = 120 mg
2 slices of toast with butter on each: 2 * ( 170mg+41mg) = 422mg
and coffee: 1 *0 = 0
The total sodium ingested is: 4 mg + 120 mg + 422 mg = 546 mg
Answer: 546 mg
