Answer:
-2.5
Since he already has saved more money than he needs its going to be a negative.
Step-by-step explanation:
1. Create a equation
a. The equation must equal 240 because we know that is the total Jack is saving for
b. He already has 260$ so we must add it within the equation
c. We add 8x because we know he gets 8$ a week but since we dont know how many weeks we will use the variable x
8x + 260 = 240
2. Get x by itself. Do this by subtracting 260 to both sides of the equal sign
8x= -20
3. Divide 8 to both sides of the equal sign
x=-2.5
recall d = rt, distance = rate * time.
let's say airplane A is going at a rate of "r", therefore airplane B is moving faster, at a rate of "r + 80".
now, after 3 hours, both planes have been travelling for 3 hours each, and say if A has covered "d" miles, then B has covered the slack of 2490 - d.
