65 The time taken by machines A B and C to execute a given t
[6.5] The time taken by machines A, B, and C to execute a given task is
A: 16 m, 9 s
B: 14 m, 12 s
C: 12 m, 47 s
What is the performance of each of these machines relative to machine A? Why?
| A 1.000, B 1.137, C 1.263 |
Solution
Convert each of the time into seconds
A. 969 seconds
B. 852 seconds
C. 767 seconds.
Now, consider the performance to be 1.000
Now the performance of B= Time taken by A/ Time taken by B= 969/852 = 1.137
This shows that B can perform 1.137 better than A.
Similarly for C Time taken by A/ Time taken by C= 969/767=1.263
This is vecause the other two takes less time compared to A.
