You are running a 10 mile race. You run the first 3 miles in 24.7 minutes. Your goal is to finish the race in less than 1 hour and 20 minutes. What should you average running time (in minutes per mile) be for the remaining miles?

Answers

Answer 1
Answer:

Answer:

Therefore you have to run every mile in ~ 8 minutes.

Step-by-step explanation:

10 miles - 3 miles = 7 miles left.

1 hour 20 minutes - 24.7 minutes= 80 minutes - 24.7 minutes

                                                       = 55.3 minutes left

Therefore, you have 55.3 minutes left to run 7 miles. But since you want to finish in LESS than 1 hour and 20 minutes, subtract the .3.  

So:

7 miles = 55 minutes

1 mile        x minutes

x minutes= 55 x 1 ÷ 7 miles

x minutes = 7.85

x minutes = ~ 8 minutes

Therefore you have to run every mile in ~ 8 minutes.

Hope this helps!

Nikki is participating in a charity walk thisweekend. She walks at a pace of 4.2 miles
per hour. How long will it take her to walk
35.7 miles?

Answers

Answer:

8.5 hours

Step-by-step explanation:

We know that it takes Nikki 1 hour to walk 4.2 miles.

We need to figure out how long it will take her to walk 35.7 miles.

This is our expression; 35.7 ÷ 4.2.

Let's go ahead and divide these two numbers.

(35.7 ÷ 4.2) = 8.5

So It will take Nikki 8.5 hours to walk 35.7 miles.

Have an excellent day!

Circle B has an area of 675 sq meters. What is the diameter of Circle B.

Answers

Answer:

area = \pi {r}^(2)

675= 3.14× r²

r²= 675/ 3.14

r²=214.968

r = √(214.968)

radius=14.66 meters

diameter= 2× radius

diameter= 2× 14.66

diameter = 29.32 meters
