Answer:
7:45
Step-by-step explanation:
Since they both turn red at differnt times, you have to find a multiple to find the time they will be both on
Main St: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98, 105
Elm St. 15, 30, 45, 60, 75, 90, 105
They will both turn on 105 minutes or 1 hour and 45 minutes from 6
6 + 1 hr 45 min = 7:45
Let s = Car B's speed
Car B is 15 mph faster than A, therefore
(s - 15) = Car A's speed
Write a distance equation; dist = speed * time
2(s-15) = 1.5s
2s - 30 = 1.5s
2s - 1.5s = 30
.5s = 30
s = 60 mph is car B's speed
Confirm this find the distances, they should be equal
2 (60-15) = 90
1.5 (60) = 90
Well, a fraction is essentially a division expression. So A and C are out because those are addition expressions.
B and D are left. Because a is being divided by b, instead of b divided by a, the only answer left would be D.

Answer:
Dependent variable: $10/hr Independent Variable: Number of Hours spent on the bike. Equation y=10h
Step-by-step explanation:
The $10/hr is dependent because that never changes, the independent variable however changes. The equation will matter upon the independent variable h.
Hope this helps.
