Answer:
C. 51
Step-by-step explanation:
I did this already on a test and got the answer right.
C
let's sort the numbers first :
35, 38, 43, 45, 51, 51, 55, 62, 64
the median is now the middle number of the sorted list :
51
Add all the times together:
10 + 25 + 15 = 50 minutes total.
For the ratio divide the time for weights by total time:
25/50 which reduces to 1/2
The ratio is 1/2
2:3 And. 6:9
3:4 And 9:12
8:5 and 16:10
1:2. And 3:6
196
