A = 115 + 1/2 (p + s)
you subtract 115 from both sides, and you get
A - 115 = 1/2 (p + s)
now you multiply by 2 on both sides, and you get
(A - 115) * 2 = p + s
NOTE: I DISTRIBUTED 2 IN THE FOLLOWING EQUATIONnow you subtract p on both sides to get s by itself and you get
2A - 230 - p = s
so the final answer is .......
The speed of the first runner is 1.78 mph while for the second runner is 2.22 mph
<h3>
Speed</h3>
Speed is the ratio of total distance to total time taken. It is given by:
Speed = distance / time
Let a represent the speed of the first runner and b for the second runner. Hence:
a = (4/5)b
After 30 minutes (0.5 hour), the runners are 2 miles apart, hence:
a = d₁ / 0.5
d₁ = 0.5a
Also:
b = d₂/0.5
d₂ = 0.5b
d₁ + d₂ = 2, hence:
0.5a + 0.5b = 2
0.5(4/5)b + 0.5b = 2
b = 2.22 mph
a = (4/5) * 2.22 = 1.78 mph
The speed of the first runner is 1.78 mph while for the second runner is 2.22 mph

Step-by-step explanation:
Answer:
Choice B
Step-by-step explanation:
This is shown by following the simple multiplication rule that has been set, which is x*6=y. By doing this, we get:
Choice A: 1 * 6 = 6
Choice B: 2 * 6 = 12
So as you can see, choice A would be incorrect, and choice B would be correct.
