Best ResponseYou've already chosen the best response.0so final height  initial height = distance. Think sea level as 0, so 12 1/2  48 3/5 = ?

Best ResponseYou've already chosen the best response.0and then take the absolute value of the answer, because distance can't be negative.

Best ResponseYou've already chosen the best response.0Wait...wouldn't it be 48 3/5  12 1/2?

Best ResponseYou've already chosen the best response.0\[\left(48+\frac{3}{5}\right)\left(12\frac{1}{2}\right)=\frac{174}{5}=34+\frac{4}{5} \]

Best ResponseYou've already chosen the best response.0vicky191, think about it this way. if a plane starts 2m above ground and stops at 4m above ground, Wouldn't you do 42 to find the distance? ( you could also do 24 and take the absolute value. Either way the answer will be 2m.) Similarly, you could do 12 1/2  48 3/5 as well as 48 3/5  (12 1/2).
