Hi there! So, you already know Kareem's time, which is 8 minutes 43 seconds. Stacey finished after Kareem, which means her time was lover and Elian finished 2 minutes sooner than Stacey. To find the times, you have to add and subtract, depending on the situation. If you are adding time and the seconds exceed 60, you have to add 1 into the minutes section. With that bridals, here are the answers if you add correctly.
if you do not understand 2 then here is a explanation you find slope so take any two point then go over then up the amount over is on the bottom and the amount up on top then simplify if needed
