Hello! Can someone help with this question?
IgorC [24]

Hello! :)

\large\boxed{\text{70 seconds}}

Use a proportion to find how many seconds are needed to fold 5 shirts.

We are given that he takes 28 seconds to fold 2 shirts:

28 sec : 2 shirts

We are not given the amount of time needed for 5 shirts, which we need to solve:

x seconds : 5 shirts

Express in a fraction:

\frac{2 shirts}{28 seconds}  = \frac{5 shirts}{xseconds}

Cross multiply and simplify:

2 * x = 5 * 28\\\\2x = 140\\\\x = 70 sec

Therefore, he needs 70 seconds to fold 5 shirts.
