12 + 5 + 7 + 6 + 6 + 4 = 40
P ( rock ) = 7 / 40

Answer:
In 3 hours, they will be 18 miles apart.
Step-by-step explanation:
Given that:
Speed of Mr. Irvine = 77mi/h
Speed of Mr. Babyak = 71mi/h
Distance to be apart = 18 miles
Let,
t be the time.
We will subtract the speeds as both the cars are driving in the same direction.
Distance = Speed * Time
18 = (77-71)t
18 = 6t
6t = 18
Dividing both sides by 6

Hence,
In 3 hours, they will be 18 miles apart.
A coefficient is the number that times (or multiplies) the variable, so your answers should be -24 and 7.
