maria ran the obstacle course each day during her gym class and recorded the follwing monday 51.6sec tuesday 58.6sec wednesday 48.3sec thurday 52.7sec on friday she ran the obstacle course again the mean (average) time for all five days is 52 seconds what was maria time friday?
Add each day's time. Divide the total by 4. That will give the average for these four days.
Or add four days time and include x. then multiply 52 by 5 after that solve for x
day time 1+2+3+4+x=52*5
To find Maria's time on Friday, we need to use the information given. We know that the mean (average) time for all five days is 52 seconds.
To calculate the mean, we need to add up the times for all five days and divide by the total number of days.
Let's add up the times:
51.6 sec + 58.6 sec + 48.3 sec + 52.7 sec + x sec (Friday's time) = 52 sec x 5 days
To find Maria's time on Friday, we need to solve for x:
(51.6 + 58.6 + 48.3 + 52.7 + x) / 5 = 52
Let's simplify the equation:
(211.2 + x) / 5 = 52
To isolate x, we can multiply both sides of the equation by 5:
211.2 + x = 260
Now, let's solve for x by subtracting 211.2 from both sides of the equation:
x = 260 - 211.2
x = 48.8
Therefore, Maria's time on Friday was 48.8 seconds.
