Answer:
6
Step-by-step explanation:
Deisha's build rate = 1 fence per 15 hours = 1/15 fences per hour
Travis's build rate = 1 fence per 12 hours = 1/12 fences per hour
Working together, their combined rate is 1/15 + 1/12 = 3/20 fences per hour
So it takes them 20/3 = 6 2/3 hours per fence
x=2y is linear and can also be writtend as y=x/2
121- 88 = 33 miles traversed in 30 minutes.
d = r*t
33 = r* (.5 hr)
Solve for r.
Average speed will be in miles per hour.
