Answer:
Total Distance = 2 miles
Step-by-step explanation:
We know D = RT where
D is distance
R is rate (speed)
T is time
First Leg:
Rate = x mph
Time = 20/60 = 1/3 hour
Hence, D = RT, Distance = x * 1/3 = x/3 miles
Second Leg:
Rate = x - 1
Time = 30/60 = 1/2 hour
Distance = (x - 1) * 1/2 = (x-1)/2
Total distance is the sum of both the legs, hence,
Total distance = 
miles
Since both the distance are equal we can equate and solve:
Plugging this x = 3 into the total distance expression, we get:
Total distance, 2 miles
So puppies will be 5x and Kittens 4 x so they combined will be 5x+4x=27
9x=27
X=3
I can help you with 11 so its 588 because I know that 600 divide by 12 equals 50 so they said they want less then 600 so I tried 49 times 12 equals 588
Using proportions, it is found that she needs 4 consecutive hits to raise her batting average to .400.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount.
Hence, the batting average is given by the <u>number of hits divided by the number of at-bats</u>.
If she gets x consecutive hits, she will have 8 + x hits in 25 + x at-bats, for an average of 0.400, hence:
8 + x = 10 + 0.4x
0.6x = 2
x = 3.33
Rounding up, she needs 4 consecutive hits to raise her batting average to .400.
