Answer:
Step-by-step explanation:
Given y = 48, x = 1/2. We will find k.
Find x.
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

Hi there,
So the problem is 2/7 ÷ 1/3
well the answer to this is 6/7
In order to solve this is to cross multiply so
2 x 3 and 7x3
which is the result of 6/7
In decimal form it is: 0.857
Hope this is correct :)
Have a great day
