Step-by-step explanation:

It would take them 120 hours to get to the same point on the path again.
Kara is traveling at half the speed of Steven. Therefore, we Steven finishes his second lap Kara will just be finishing her first lap. They will both be at the starting lap again.
It will take Kara 120 hours to complete the lap.
1800 / 15 = 120
(That is a lot of time, do you have the numbers correct?)
290-10=280
280 is one standard deviation below.
All that are above mean is 50%.
One standard deviation below is 34%.
50%+34%=84% all of these bags weigh more than 280 g.
So,
100%-84%=16% should be bags that are less than 280 g.
Answer is b) 16 %.
Maybe 6 but I’m not sure.
