So, 50 times 5 equals 250 right? So, if it were to take 10 days it would be 100 deliveries over the 400 mark. So from there you would go back two days and it would make 8 days. So the answer would be 8 days long

Answer:

40

Step-by-step explanation:

50 deliveries +50 deliveries =100 deliveries

5 days +5 Days = 10 Days

There are 100 deliveries every 10 days.

400 deliveries/10 days= 40 Days
