Answer:
The rate of the boat in still water is 40 miles per hour
The rate of the current is 10 miles per hour
Step-by-step explanation:
we know that
The speed or rate is equal to divide the distance by the time
Let
x ----> the rate of the current (miles per hour)
y ----> the rate of the boat in still water (miles per hour)
we have that
<em>going upstream </em>
----> equation A
<em>going downstream </em>
----> equation B
Solve the system of equations by elimination
Adds equation A and equation B
<em>Find the value of x </em>
therefore
The rate of the boat in still water is 40 miles per hour
The rate of the current is 10 miles per hour
Answer:
c. 13 weeks
Step-by-step explanation:
365-40=325 (to find what she needs to make)

True. To find average monthly income, multiply the net pay by the number of pay periods per year. Then, divide this yearly income by 12 months.
For example:
Daily wages:
Daily wages * 365 days = Total Wage
Total wage / 12 months = average monthly income
Weekly wages:
Weekly wages * 52 weeks = total wage
total wage / 12 months = average monthly income
