Evan walked 14 miles in 7 hours. What was his walking rate in hours per mile?

Answers

Answer:

.5 hours per mile

Step-by-step explanation:

We want hours per mile

7 hours / 14 miles

1/2 hours per mile

.5 hours per mile

Final answer:

Evan's walking rate is 0.5 hours per mile, meaning it takes him half an hour to walk one mile.

Explanation:

The question is asking for Evan's walking rate in hours per mile. To find this, you need to divide the total time taken by the total distance covered. Therefore, the walking rate would be 7 hours divided by 14 miles.

To calculate, divide 7 by 14, which equates to 0.5. So, Evan's walking rate is "0.5 hours per mile." This means it takes him half an hour to walk one mile.

Leah has 6 1/4 yards of ribbon to make bows. Each bow is made from a piece of ribbon that is 1/3 yard long. What is the maximum number of complete bows Leah can make?

Answers

Leah can make 18 complete bows. She will then have 1/4 yards of fabric left over. This is true because there are 3 thirds to a whole and there are 6 complete yards of ribbon. 3 x 6 = 18. Then we get left with an extra 1/4 yards of fabric because 1/4 is less and a third.
