Question

Suppose your friend is thinking of opening a new restaurant, and hopes to have around 16 groups of (on average) 4 customers on a typical busy evening. Each meal will take around 1.6 hours and it is expected that on average a table will be used twice in an evening. Each table and its surroundings will require 5.3 square metres of space. Assume customers arrive in two streams (e.g., at 5 pm or at 7 pm).

a. Calculate the required seating area. (Round the final answer to 1 decimal place.)
Seating area ______ m²
b. If each meal will take an average of 10 minutes to cook on a heating element, and each stove will have 4 elements, how many stoves would the restaurant require?

Assume that all 8 "tables" could come at the same time and that the kitchen should be able to cook the meal for them during the first hour of their visit. (Round the final answer to the next whole number.)
No. of stoves ______

Answer 1

Answer and Explaination:
a. To calculate the required seating area for the restaurant, we need to consider the average number of customers per group, the number of groups, and the space required per table.

Given:

Average number of customers per group = 4

Number of groups = 16

Space required per table and surroundings = 5.3 square meters

To calculate the required seating area, we can use the following formula:

Seating area = Number of groups * (Average number of customers per group / 2) * Space required per table

Seating area = 16 * (4 / 2) * 5.3

Seating area = 16 * 2 * 5.3

Seating area = 169.6 square meters

Therefore, the required seating area for the restaurant is approximately 169.6 square meters.

b. To determine the number of stoves required for the restaurant, we need to consider the average cooking time per meal, the number of elements per stove, and the total number of meals.

Given:

Average cooking time per meal = 10 minutes

Number of elements per stove = 4

To calculate the number of stoves, we divide the total cooking time by the average cooking time per stove:

Number of stoves = (Total cooking time) / (Average cooking time per stove)

Total cooking time = Number of groups * (Number of meals per table) * (Average cooking time per meal)

Number of meals per table = 2

Total cooking time = 16 * 2 * 10

Total cooking time = 320 minutes

Number of stoves = 320 minutes / 10 minutes per stove

Number of stoves = 32

Therefore, the restaurant would require 32 stoves.
