Question

If Sarah irons 12 shirts in 18 minutes. Write a two linear equation that represents the number of small shirts she can iron in any given time interval (t).

Answer 1

s = 2/3t

Explanation:

For some time (t) in minutes, Sarah can iron "s" shirts:

s = (12/18)t

s = 2/3t

_____

If you need to, you can start with a proportion:

shirts/minutes = s/t = 12/18

Then multiply by t to get the above equation.
