Solving a word problem using a one step Linear inequality

Question

Lisa will run more than 36 miles this week. So far, she has run 20 miles. what are the possible numbers of additional miles she will run.

Answer 1

M > 36-20

M> 16

she will run at least 16 more miles,

maybe 16, maybe 17, or up to a physical limit for running in one week, perhaps 80 max per day, 7x80=560 for a week. 560-20 = 450

16< M < 450, much lower upper boundary unless she's an ultra marathon runner, one of those runners into doing 100 mile marathons, 4 1/2 in one week.
