for an advanced jump is than a beginner jump.
part a
what are the hidden questions you need to
answer to solve the problem?
beginner jump
the advanced jump distance is
8 times the beginner jump distance.
the total length of a beginner jump hill
is 3 times the beginner jump distance.
part b
how much longer is the total length of an advanced jump hill than a
beginner jump hill? write equations and explain how to solve the hidden
questions and the original question.
part
is the answer you found in part b reasonable? explain.
3. how much greater is the height of an advanced jump than an
intermediate explain

An annual marathon covers a route that has a distance of approximately 26 miles. winning times for this marathon are all over 2 hours. the following data are the minutes over 2 hours for the winning male runners over two periods of 20 years each. earlier period 14 12 15 22 13 10 19 13 9 14 20 18 16 20 23 12 18 17 6 13 recent period 7 11 7 14 8 9 11 14 8 7 9 8 7 9 9 9 9 8 10 8 (a) make a stem-and-leaf display for the minutes over 2 hours of the winning times for the earlier period. use two lines per stem. (use the tens digit as the stem and the ones digit as the leaf. enter none in any unused answer blanks. for more details, view how to split a stem.) minutes beyond 2 hours earlier period 0 1 2 (b) make a stem-and-leaf display for the minutes over 2 hours of the winning times for the recent period. use two lines per stem. (use the tens digit as the stem and the ones digit as the leaf. enter none in any unused answer blanks.) minutes beyond 2 hours recent period (c) compare the two distributions. how many times under 15 minutes are in each distribution
