I being the intercenter of the triangle means that IA = BI= CI
CI = 52-2X
AI = 3X +7 ==> AI = IC ==> 3X+7 = 52-2X SOLVE FOR X
3X+2X = 52-7 ==> 5X = 45 & X =9
IF X = 9 THEN IC = 52-2(9) = 34. IC =34
Answer:
300 seconds = 5 minutes
Step-by-step explanation:
At first convert the time in minutes which is
5.75 * 60 = 345 seconds
No as the average is 345 seconds at starts from 45 so we subtract that time from 45 seconds
345-45 = 300 seconds (Mean)
So 300 seconds = 300/60 = 5 minutes
So the Accurate mean is 5 minutes
