Answer:
- Kyle, 67 mph
- Cooper, 62 mph
Step-by-step explanation:
Their difference in distance is 87.1 -80.6 = 6.5 miles. Since their difference in speed is 5 mph, it took them (6.5 mi)/(5 mi/h) = 1.3 hours to achieve that separation.
Kyle's speed is 87.1 mi/(1.3 h) = 67 mi/h.
Cooper's speed is 80.6 mi/(1.3 h) = 62 mi/h. (5 mi/h slower)
Kyle is driving 67 mph; Cooper is driving 62 mph.
_____
<em>Alternate solution</em>
The ratio of their speeds is 87.1/80.6 = 67/62. The difference in ratio units happens to equal their difference in miles per hour, so their speeds must be 67 and 62 miles per hour.

Answer:
12.5%
25%
50%
25%
12.5%
50%
Step-by-step explanation:
In this case, each event has a probability of 1/2, because the coin only has two faces, dog or cat.
Therefore the probability will be the multiplication of the probability of each event.
What is the probability of getting three dogs?
(1/2) * (1/2) * (1/2) = 0.125 = 12.5%
What is the probability of getting 2 cats?
(1/2) * (1/2) = 0.25 = 25%
What is the probability of getting 1 dog?
(1/2) = 0.5 = 50%
What is the probability of getting 2 dogs?
(1/2) * (1/2) = 0.25 = 25%
What is the probability of getting 3 cats?
(1/2) * (1/2) * (1/2) = 0.125 = 12.5%
What is the probability of obtaining 1 cat?
(1/2) = 0.5 = 50%
