Answer:
21 miles per hour
Step-by-step explanation:
Let w represent the wind speed. Then the travel time is ...
400/(329 +w) = 352/(329 -w)
400(329 -w) = 352(329 +w)
(352+400)w = 329(400 -352)
w = (400 -352)/(400 +352)·329 = 48/752·329 = 21
The wind speed is 21 miles per hour.
None of these is correct, the answer to that addition problem would be 30 and none of the answers listed equal to that amount
$9.76 Because 7% plus 15% is 22% 22% of 8 is $1.76 plus $8 is $9.76
