Sounds as tho' something's missing here. What is "the average" You haven't given it.

If "the average" were 5, then 1 is 4 units below the average, 4 is 1 unit below the average, and 6 is 1 unit above the average.

Check the original problem. Isn't the average given there?

Lupe can ride her bike at a rate of 20 mph when there is no wind. On one particular day, she rode 2 miles against the wind and

WARRIOR [948]

Hello there! Your answer should be 4 mph. Reasoning:

2 = (20 - x) * t

3 = (20 + x ) * t

Time is the same for both equations. Solve for T.

2/(20-x) = 3/(20+x)

the answer is 4 mph.

Please tell me if I was right!
