One afternoon, kassims sandwich shop sells 15 sandwiches in 45 minutes. If the shop continues to sell sandwiches at the same rate, about how many sandwiches will the shop sell in 3 hours?
15 sandwiches /.75 hr * 3 hr = 60 sandwiches
To find out about how many sandwiches the shop will sell in 3 hours, we need to calculate the rate at which sandwiches are being sold per minute, and then multiply it by the number of minutes in 3 hours.
Since the shop sold 15 sandwiches in 45 minutes, we can divide the number of sandwiches by the number of minutes to find the rate:
Rate = Number of sandwiches / Number of minutes
Rate = 15 sandwiches / 45 minutes
Now, we need to calculate the rate per minute:
Rate per minute = Rate / Number of minutes
Rate per minute = 15 sandwiches / 45 minutes
To find out how many sandwiches will be sold in 3 hours, we multiply the rate per minute by the number of minutes in 3 hours:
Number of sandwiches in 3 hours = Rate per minute × Number of minutes in 3 hours
Number of sandwiches in 3 hours = (15 sandwiches / 45 minutes) × (60 minutes/hour × 3 hours)
Let's do the calculation:
Number of sandwiches in 3 hours = (15 / 45) × (60 × 3)
Number of sandwiches in 3 hours = (15 / 45) × 180
Number of sandwiches in 3 hours = 5 × 180
Number of sandwiches in 3 hours = 900 sandwiches
Therefore, the shop will sell about 900 sandwiches in 3 hours if it continues to sell sandwiches at the same rate.
