A) 1 and 2
That is the correct answer
Answer:
It will take 10 hours.
Step-by-step explanation:
We know distance = rate * time
Sally's rate = 55
Jim's rate = 65
We want Jim to be 100 miles ahead of Sally
The time will always be the same.
d =Sally's distance
Sally
d = 55t
Jim
d+100 = 65 t
We know have 2 equations with 2 unknowns. Substitute d= 55t into Jim's equations
55t + 100 = 65t
Subtract 55t from both sides.
55t-55t + 100 = 65t-55t
100 = 10t
divide each side by 10
100/10 = 10t/10
10 = t
12...? I think?
Since she has 9 left and it only says that she gave 3 away..
G = 2.5
Use inverse operations. 9 / 3.6 = 2.5.
-1/5, -2/3, .04, 2
Hope this helps :)
