Answer:
Shad's cost per use will be $ 2.80.
Step-by-step explanation:
Since Shad Yarbrough wants to consider the cost per use of a high-end desk top computer he is considering for his web site business, and the computer costs $ 1,750 and has a life expectancy of four years, if Shad feels he would use the computer three days a week, on average, to determine what is Shad's cost per use, the following calculation must be performed:
Weeks per year = 52
52 x 4 = 208
208 x 3 = 624
1750/624 = X
2.80 = X
Thus, Shad's cost per use will be $ 2.80.
20 minutes is 1/3 of an hour, so an hour can be split into 3 20 minute sections.
They run 4 miles each 20 minute section equals 4 x 3 = 12 miles per hour.

Answer:
24/35 hours or 0.69 hours
Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
Let
x-----> distance traveled by John
(24-x) ----> distance traveled by Ramona
The time is equal to divide the distance by the speed
so
x/20=(24-x)/15
15x=20(24-x)
15x=480-20x
15x+20x=480
35x=480
x=480/35 miles
the time is equal to
t=x/20
t=480/(20*35)=24/35=0.69 hours
