Answer :

The equation of the machine that can make 5 miles of ribbon in an hour

  • r = 5x

in 8 hours it produces 40 miles

The equation of the machine that can make 8 miles of ribbon in an hour

  • r = 8x

in 8 hours it produces 64 miles

How to find the required equations

From the problem it can be deduced that

A machine can make 5 miles of ribbon in an hour

5 mile = 1 hour

how much ribbon, r, is made after x hours is solved by

5 mile = 1 hour

r miles = x hours

cross multiplying

r = 5x

in 8 hours

r = 5x = 5 * 8 = 40 miles

in 8 hours the machine makes 40 miles of ribbon

Another machine can make 8 miles of ribbon in an hour

8 mile = 1 hour

how much ribbon, r, is made after x hours is solved by

8 mile = 1 hour

r miles = x hours

cross multiplying

r = 8x

in 8 hours

r = 8x = 8 * 8 = 64 miles

in 8 hours the machine makes 64 miles of ribbon
