This kind of problems requires to add the working velocities. The total velocity is the sum of the individual velocities.
Anita's velocity = 1 pool/8 hours
Chao's velocity = 1 pool/6 hours
Combined velocity 1/8 + 1/6 = (3 + 4)/24 = 7/24 pool/hour
Time = 1 pool / (7/24) pool/hour = 24/7 hour =3.43 hours
He needs 3 1/4 more yards of fabric because 5.5 - 2.25 = 3.25
Answer:
- ... construction of parallel lines (parallel to AB through C)
- ... width to IJ
Step-by-step explanation:
Construction of parallel lines is accomplished by copying an angle. Here, the steps shown will result in copying the angle IDJ if the distance IJ is marked on the arc through k, then a line drawn through C and the point just marked.
