Question

the average time to run a mile for members of your gym class is 7 minutes and 4 seconds. You want your time to be within 5 seconds of the class average. Rewrite the class average as seconds, then write and solve an absolute value inequality for the difference between time,t, and the class average. I have no clue how to solve this problem, can someone help me please?

Answer 1

how many seconds do you have in 7 minutes and 4 seconds?

Answer 2

424 seconds

Answer 3

ok, so, you want your time "to be within 5 seconds of the class average" means your time is \(424\pm5\) right?

Answer 4

so, 424+5 =?
and 424-5=?

Answer 5

do it, not done yet

Answer 6

429 and 419
