Allen runs 8 miles in 3 hour, how long does it take him to run 3 miles

divide 8 miles by 3 hours to find how many miles he runs in 1 hour:

8 /3 = 2 2/3 miles in one hour.

Now divide 3 miles by 2 2/3 miles per hour:

3 / 2 2/3 = 1 1/8 hours  (1 hour 7.5 minutes) to run 3 miles.

1 1/8 hours = time

Step-by-step explanation:

To find the rate, we take the distance and divide by the time

8/3 = 8/3 miles per hour

We know that distance = rate * time

We need to find time

distance/ rate = time

3 miles/ 8/3 miles per hour = time

Copy dot flip

3 * 3/8 = time

9/8 hours = time

1 1/8 hours = time

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
