Josie and Rushawn ran a race. Josie finished in 329 seconds. Rushawn finished less than 60 seconds later. Which inequality

Neporo4naja [7]

Answer: r < 389

Step-by-step explanation:

Hi, to answer this question we have to write an inequality:

Rushawn's possible finishing times (r) must be less (<) than Josie's finishing time (329) plus 60 seconds.

Mathematically speaking:

r < 329+60

r < 389

So, the correct option is the last one.
