Answer:

Trina ran \frac13 of the distance ran by Micheal.

Step-by-step explanation:

To find: Which fraction of Michael's distance did Trina run.

Solution:

Let the distance run by Michael be 'x'.

Now Given:

James had run 1/2 of Michael's distance

So we can say that;

Distance ran by James = \frac12}x

Also Given:

Trina had run 2/3 the distance James ran.

So we can say that;

Distance ran by Trina is equal to \frac23 multiplied by distance ran by James.

framing in equation form we get;

Distance ran by Trina = \frac23\times\frac12x =\frac13x

Hence Trina ran \frac13 of the distance ran by Micheal.

Nikita ran a 5-kilometer race in 39 minutes (0.65 of an hour) without training beforehand. In the first part of the race, her av
s344n2d4d5 [400]

Nikita's distance from her for the second part of the race was 1.5 kilometers.

Since Nikita ran a 5-kilometer race in 39 minutes (0.65 of an hour) without training beforehand, and in the first part of the race, her average speed was 8.75 kilometers per hour, while for the second part of the race, she started to get tired, so her average speed dropped to 6 kilometers per hour, to determine which expression represents Nikita's distance for the second part of the race the following calculation must be performed:

  • 8.75 x 0.65 + 6 x 0 = 5.68
  • 8.75 x 0.50 + 6 x 0.15 = 5.275
  • 8.75 x 0.40 + 6 x 0.25 = 5
  • 100 = 60
  • 40 = X
  • 40 x 60/100 = X
  • 24 = X
  • 39 - 24 = 15
  • 15 = 1/4 hour
  • 6/4 = 1.5

Therefore, Nikita's distance from her for the second part of the race was 1.5 kilometers.
