The answer would be L because it is away from the rest ( outlier)
Hope I wrote this clearly
-n/3=4
-n/3 x 3=4 x 3
-n=12
-n/-1=12/-1
n=-12
I'm assuming your answers are listed as 1 through 4, not decimals.
You simply take 12 - 8 = 4, but ten min. less than that, so 3 hr, 50 min. then add 3 hr 45 min, totaling 7 hr 35 min. , which is closest to 7 and 1/2 hours, the second option.
