Question

Austin began a repiping job with 26 yards, 2 feet, 5 inches of pipe. When he finished the job, he had 13 yards, 2 feet, 7 inches. How much pipe did he use for the repiping job?

Answer 1

Answer:

12 yd, 2 ft, 10 in

Step-by-step explanation:

we know that

1 yard is -------> 36 in

1 yard is -------> 3 ft

1 ft is ---------> 12 in

we have

when the work started

26 yards, 2 feet, 5 inches convert to inches

26*36+2*12+5=965 in

when the job was finished

13 yards, 2 feet, 7 inches convert to inches

13*36+2*12+7=499 in

Find the difference

965-499=466 in

a) convert to yards

466/36=12.9444 yd

12 yards is-------------> 12*36=432 in

so

466 in=12 yd +(466 in-432 in)

466 in=12 yd +34 in

b) convert 34 in to feet

34/12=2.832 ft is--------> 2*12=24 in

34 in=2 ft+(34 in-24 in)

34 in=2 ft+10 in

therefore

466 in=12 yd +2 ft +10 in
