Step1: Identify the problem type

We need to find the number of words typed per minute, which is a rate problem. The formula for rate is total words divided by total minutes.

Total words = 189, Total minutes = 7.

Step3: Calculate the rate

Rate = $\frac{189}{7}$ = 27.

Step1: Identify the problem type

We need to find the time per problem, so we divide total time by number of problems.

Step2: Extract values

Total time = 24 minutes, Number of problems = 16.

Step3: Calculate time per problem

Time per problem = $\frac{24}{16}$ = 1.5 minutes.

Step1: Identify the problem type

We need to find the number of pages read per minute, which is a rate problem. The formula is total pages divided by total minutes.

Step2: Extract values

Total pages = 108, Total minutes = 9.

Step3: Calculate the rate

Rate = $\frac{108}{9}$ = 12 pages per minute.
