A Supermarket manager hired one packager who can pack 15 boxes every two minutes. After some time the manager noticed that packaging is too much work to be done by one person, so they hired another packager who can pack 15 boxes every three minutes. How many minutes will it take these two packagers, working together, to pack 500 boxes?

answer : the point moved thirteen places to the right

on the number line, a point is moved from -8 to 5

on a number line, negative numbers on the left side of 0   and positive numbers on the right side of 0.

to move from -8 to 5 , we move to the left

start from -8 , move to -7 then -6 then -5 then -4 then -3 then -2 then -1 then 0 then 1 then 2 then 3 then 4 and finally 5

so we moved 13 placed to the right.

the point moved thirteen places to the right
