Multiply 575 by .16
Multiply 750 by 1.02
25% is 1/4 of 100% so multiply 80 by 4.
38/33=1.151515...=1.(15) or 1.15 and put a bar above repeating part - a bar above 15.
R=rate of boat in still water
c=rate of current
d=rt
since you're given that the time it takes to travel the same distance downstream and upstream, your equation will be d_1=d_2, or rt=rt
the rate upstream is r-c and the rate downstream is r+c (because the boat's and river's rates add up)
since you know t_1 and t_1 are 5 and 3, you can now set up 2 equations
<u>5*(r-c)=45</u> because (time upstream)*(rate upstream)=distance=45 miles
r-c=45/5=9
<u>3*(r+c)=45</u>
r+c=45/3=15
r-c=9 and r+c=15, so r=12 mi/h and c=3 mi/h

Answer:
550 miles.
Step-by-step explanation:
First, we know that each 1,4 (quarter) of an inch equals 50 miles. and we know that four 1,4s equals one. so, using that information, we have 2 3/4. so the 2 has 8 quarters, and then we have 3 quarters left. so we add the 8 quarter's and the 3 quarter's, to get 11. and since each quarter is equal to 50 miles, we multiply 50 by 11.

The diagram for this exercise is attached below. We have two linear functions 
and the following relationship:
From the graph, we know that:
Then, substituting into the relationship:
