The time taken by the machines to execute a given task is:

A: 15 m, 20 seconds

B: 12 m, 10 seconds

C: 10 m, 45 seconds

1. What is the performance of machine B relative to machine A? Enter your numerical answers below. Enter your answers to two places after the decimal (i.e., 3.56).

2. What is the performance of machine C relative to machine A? Enter your numerical answers below. Enter your answers to two places after the decimal (i.e., 3.56).

Answer 1

1. performance of machine B relative to machine A.

   Time taken by machine A / Time taken by machine B

   = 15m 20 sec / 12m 10 sec

   = 920 / 730

   = 1.26

2. performance of machine C relative to machine A.

   Time taken by machine A / Time taken by machine C

   = 15m 20 sec / 10m 45 sec

   = 920 / 645

   = 1.42
