Question

a store manager timed janette to see how long it would take her to fold and put away a sweater, a shirt, a pair of pants, and a scarf. it took her 26.1 seconds for the shirt, 24.3 seconds for the sweater, 32.8 seconds for the pants, and 18.2 seconds for the scarf. what was the average time it took janette to fold and put away all four items?
○ 25 seconds
○ 25.4 seconds
○ 25.35 seconds
○ 26.1 seconds

Explanation:

Step1: Sum the times

First, we need to sum up all the times. The times are 26.1, 24.3, 32.8, and 18.2 seconds. So, \(26.1 + 24.3 + 32.8 + 18.2\). Let's calculate that: \(26.1+24.3 = 50.4\), \(50.4 + 32.8 = 83.2\), \(83.2 + 18.2 = 101.4\).

Step2: Calculate the average

To find the average, we divide the total sum by the number of items (which is 4, since there are 4 items: shirt, sweater, pants, scarf). So, the average is \(\frac{101.4}{4}\). Calculating that: \(101.4\div4 = 25.35\).

Answer:

25.35 seconds
