Peak height vs Total change in height: Activity 5 Jumping on the moon

[Alan Nauertz]

Help!

Page 35 of Student edition states that peak distance on moon is 7.6 m compared to peak distance on Earth of 2.65.  NOT 6 times as much because the value that is 6 times as much is when comparing change in height from ready position to peak position.  Fine, I get that.  In this example, the peak is about 2. 9 times higher.   The total change (center of gravity I suppose)  is 6 times is much.

Why then in Teachers edition p 24 for  PTG # 2 do they state a person can jump more than 6 times higher on the moon.  This is so misleading to me because you'ld think the basketball hoop should be more than 60 feet (10 x 6) when in reality we can only jump 2.9 times higher or about 30 feet (to touch the rim).
