Question

5 bridesmaids want to make 325 decorations for a wedding. Each decoration takes about 2 1/2 minutes to make. Which response gives the best estimate for the amount of time each bridesmaid will spend making decorations?

Answer 1

162.5 minutes OR 2.71 hours OR 2 hours and 42 minutes

Explanation:

325 × 2.5 = 812.5

812.5 ÷ 5 = 162.5

Each bridesmaid will spend 162.5 minutes making decorations.

Answer 2

Each bridesmaid will spend
`162(1)/(2)\text{ minutes}` making decorations.

Explanation:

We are given the following information in the question:

Total number of bridesmaid = 5

Total number of decorations to be done = 325

Time taken to do 1 decoration =
`2(1)/(2)\text{ minutes}`

Amount of time each bridesmaid will spend making decorations =

`\text{Number of decorations to be done by each bride}* \text{Time taken to do 1 decoration}\\\\=\displaystyle\frac{\text{Total number of decorations}}{\text{Total number of bridesmaid}}* \text{Time taken to do 1 decoration}\\\\=(325)/(5)* 2(1)/(2) = (325)/(5)* (5)/(2)\\\\= (325)/(2) = 162(1)/(2)\text{ minutes}`

Thus, each bridesmaid will spend
`162(1)/(2)\text{ minutes}` making decorations.
