To solve this problem, we need to consider the average delivery time and the available time.
Given that the average delivery time is 40 minutes, we can determine the number of deliveries each rider can make within 1 hour (60 minutes).
Using the fact that there are 60 minutes in an hour, we can calculate the number of deliveries per rider:
Deliveries per rider= Total time available/Average delivery time
Deliveries per rider = 60/40 =1.5
Since we cannot have fractional riders, we need to round up the number of deliveries per rider to the nearest whole number. Therefore, each rider can make 2 deliveries within 1 hour.
To find the number of delivery riders needed for 100% delivery of the orders, we divide the total number of orders by the number of deliveries per rider:
Number of Delivery riders= Total number of orders/Deliveries per rider
Deliveries per rider = 100/2 =50
Therefore, you would need 50 delivery riders to achieve 100% delivery of the 100 orders within 1 hour.
