Answer:

distance=rate*time

2520=(r)(3)+(r+90)(3)    (they both travel for 3 hours)

2520=3r+3r+270

2520-270=6r

2250=6r

r=2250/6

r=375 mph

r+90=375+90=465 mph

A 18 -person road crew is scheduled to finish repairing a highway in 10 days. On the morning of the fifth day, several workers o
Pavlova-9 [17]

Answer:

<u>9 workers finished the repairs, therefore 9 members of the original crew were removed. </u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Original crew scheduled to finish repairing a highway = 18 person

Number of days remaining to finish the work = 10 - 4 = 6 days

Number of days that the rest of the crew finished the repairs = 12 days

2. How many workers were removed from the crew?

We will use Inverse Rule of Three to answer this question because the less workers the crew has the more time it will take them to finish the repairs, as follows:

Workers                Days

     18                        6

      x                        12

12x = 18 * 6 (Inverse Rule)

12x = 108

x = 108/12

x = 9

<u>9 workers finished the repairs, therefore 9 members of the original crew were removed. </u>
