Answer:
(a) b = (4/7)c
(b) Bill: 40 shingles/hour; Chip: 70 shingles/hour
Step-by-step explanation:
Let b and c represent Bill's and Chip's rates in shingles per hour, respectively. Then we have ...
7b = 4c
c - b = 30 . . . . shingles per hour difference in rates
(a) Bill's rate in terms of Chip's rate can be found by dividing the first equation by 7
b = (4/7)c . . . . . Bill's rate is 4/7 of Chip's rate
__
(b) To find the rates, we can multiply the second equation by 7 and substitute using the first equation:
7c -7b = 210
7c -4c = 210
c = 210/3 = 70
b = (4/7)(70) = 40
Bill's rate is 40 shingles per hour; Chip's rate is 70 shingles per hour.

<u>The correct answer is that 600 miles per hour are equivalent to 965.4 kilometers per hour</u>
Step-by-step explanation:
1. Let's check the information given to resolve the question:
Convert 600 miles per hour to kilometers per hour
2. Let's proceed with the conversion:
1 mile per hour = 1.609 kilometers per hour
then:
600 miles per hour = 600 * 1.609 kilometers per hour
600 miles per hour = 965.4 kilometers per hour
<u>The correct answer is that 600 miles per hour are equivalent to 965.4 kilometers per hour</u>
