Answer:

1 min 45 sec

Step-by-step explanation:

First convert 14 min to seconds.

14 x 60 = 840s

Now we can use ratios to find the answer

840s : 800m

Divide both sides by 8

105s : 100m

105s is 1 minute and 45 seconds

The time, t, it takes a runner to cover a specified distance is inversely proportional to the runner's speed. If Jann Avery runs
Sveta_85 [38]

To solve this problem you will need this tool, it is the formula of speed :

<em>speed = distance/time</em>

(I suggest you to remember this one for life, it is a really useful one)

Let's check how long that Jackie nice dude will take to finish the race...

Jann avery runs at an average of 6 mph (miles per hour), so we already got the speed for our formula. And she will finish the race in 2.1 hours so we got the time. What do we miss ? The distance.

Let's write what we already know to solve this puzzle :

6 = d / 2.1

Where d is that unknown distance..  So we are in front of an equation here let's solve it :

d / 2.1 = 6

d = 6 * 2.1

d = 12.6 miles

Now that we know that distance, for the race, we can see if that poor Jackie Donofrio has all his chances to catch Jann Avery...

We already know his speed... and since we have the distance, we write :

4 = 12.6 / t

Where t is the unknown time, for Jackie, to finish the same race. Let's solve the equation :

4t = 12.6 (we multiplied t on each side of the equation)

t = 12.6 / 4

t = 3.15

Jackie Donofrio, who runs at 4 miles per hour, will finish the race in 3.15 hours

Good Luck
