Question

Ashley recently opened a store that uses only natural ingredients. She wants to advertise her products by distributing bags of samples in her neighborhood. It takes one person 2/3​ of a minute to prepare one bag. How many hours will it take Ashley and 4 of her friends to prepare 1575 bags?

Answer 1

3 hours 30 minutes

Explanation:

Step 1: Time taken to prepare 1 bag for 1 person

                                      = $\frac{2}{3}$ of a minute

                                      = $\frac{2}{3}$ × 60

                                      = 40 seconds

Time taken to prepare 1575 bags for 1 person

                                      = 1575 × 40

                                      = 63000 seconds

Time taken to prepare 1575 bags for 5 persons (Ashley + 4 friends)

                                      = $\frac{63000}{5}$

                                      = 12600 seconds

Step 2: To convert 12600 seconds into hours

                           1 hour = 3600 seconds

           12600 seconds = $\frac{12600}{3600}$

                                      = 3 hours 30 minutes

Hence Ashley and 4 of her friends will take 3 hours 30 minutes to prepare 1575 bags.
