Answer:
1. 40 days
If the company makes 50 deliveries in 5 days, he makes 50/5=10 deliveries per day. Therefore, 400 deliveries will take 400/10=40 days.
2. His painting rate is 850 ft^2 per hour
3.Take 1 min = 55 words as a conversion factor. In order to achieve the words that a programmer could type, multiply the given 11 minutes to the conversion factor. Thus, it is viewed as (55 words/ 1 minute ) x 11 minutes in order to cancel some units, the answer would be 605 words.

all we need to do is figure out what we multiplied by 15,000 to get 300,000 all we have to do is divide 300,000 by 15,000. here is the math:)
300,000/15,000 = 20
so we got 20!!
just multiply that by the 1 in the first fraction to get x in the second fraction:)
your answer: B 20
