Step 2:

Select a current speed of the water in mph.

Step 3:

Step 4:

Select the number of hours that your friend or family member made the same trip with the current (this should be a smaller number, as your friend or family member will be traveling wi

Answer 1

Step 5:

Write out the word problem you created and calculate how fast your friend or family member was traveling in still water. Round your answer to the nearest mph.

Answer 2

good lord

Answer 3

I know but i am not good with coming up with word problems

Answer 4

lets make it easier
make the current speed 10 mph
george boats against the current for 3 hours and with the current for two hours

Answer 5

alright

Answer 6

now we want the speed of the boat in still water.

lets call this rate R, so rate with current is R+10 and rate against current is R- 10

since distance equals rate times time, and we know the distance there and back are the same, we can write
\[D=(r+10)\times 2=(r-10)\times 3\] and solve for rate

Answer 7

\[2r+20=3r-30\]
\[20=r-30\]
\[r=50\] nice and easy

Answer 8

that's the answer ?

Answer 9

answer is rate in still water is 50 mph so rate with the current was 60 mph and against the current was 40 mph

Answer 10

we can even find the distance traveled if you like since
\[D=RT\] we should have
\[D=2\times 60=120\] and also
\[D=3\times 40 =120\] so we have checked the answer and it works

Answer 11

Thank You so much!
