Answer:

Steven is faster than Michelle by covering 0.64 meters more per second than that of Michelle.

Step-by-step explanation:

Given:

Steven swam 200 m in 25.7 seconds while Michelle finished in 28 seconds.

So, speed of Steven is, S_{Steven}=\frac{Distance}{time}=\frac{200}{25.7}=7.78\ m/s

Speed of Michelle is, S_{Michelle}=\frac{Distance}{time}=\frac{200}{28}=7.14\ m/s

Now, to find how much faster did  Steven swim than Michelle, we need to get the difference between their speeds.

Speed of Steven - Speed of Michelle

7.78-7.14

=0.64\ m/s

So, Steven is faster than Michelle by covering 0.64 meters more per second than that of Michelle.

Desmond spends $800 per month on fixed expenses. Desmond earns $10,00 per hour,
Elis [28]

Answer:  160 hours

============================================================

Explanation:

He earns $10.00 an hour. Let x be the number of hours worked in a month. So 10x represents how much he earns after working x hours.

If he spends $800 per month on fixed expenses, and wants this to be 50% of his total earnings, then this must mean that the other 50% is for other things (eg: spending on a vacation or putting it to savings). So his goal is to earn 800+800 = 1600 dollars per month.

Set 10x equal to this and solve for x

10x = 1600

x = 1600/10

x = 160

He needs to work 160 hours a month.

-------------------------------

Extra info:

Divide 160 over 4 (the approximate number of weeks in a month) and we see that he'll need to work 160/4 = 40 hours a week

If he only works Monday through Friday, that's 5 days of the week. So he'll put in 40/5 = 8 hours per day.

So his goal of working 160 hours per month is reasonable. Keep in mind that this doesn't include factors like him missing time from work due to being sick (unless he has paid sick leave).
