8. a kayaker spends 2 hours paddling up a
stream from point a to point b, quickly turns
her kayak around, and immediately heads
back downstream. it takes her only 1 hour to
float back down the stream from point b to
point a. if points a and b are 6 miles apart,
what was the kayaker's average rate of
speed in miles per hour?
a. 12 mph
b. 6 mph
c. 4 mph
d. 2 mph

.

D. 2 mph

Step-by-step explanation:

You would add up her total time going upstream and down stream, so 2+1 hours = 3 hours. Then, since speed = distance divided by time, you would divide 6 by 3 to get 2 mph.

answer: okw

step-by-step explanation:

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
