First we write the kinematics equations:
a
v = a * t + vo
r = a * (t ^ 2/2) + vo * t + ro
For Wanda we have:
a = 0
v = 5
r = 5 * t
For Dave we have:
v = 10
r = 10 * (t-120)
To solve the system of equations, we graph both functions and see where
they intersect.
We have to intersect in the ordered pair:
(t, r) = (240, 1200)
answer
If they continue walking at these rates, Dave catch up to Wanda in 240s (1200 ft)

Answer:
14 or
Step-by-step explanation:
Turn your fractions into improper and make them have the same denominator
+
=
Leave it as is or simplify to 14
You probably made a typing error in writing s = -3 and wrote s - = 3 instead.
The given expression is:
Substituting the given value of s in the previous equation, we get:
Thus the value of given expression becomes -46 for s = -3
