Using equations we now know that the distance of the first part of the Yuna's swim is 0.7 miles.

What are equations?

  • A mathematical statement that has an "equal to" symbol between two expressions with equal values is called an equation.
  • As in 3x + 5 Equals 15, for instance.
  • Equations come in a variety of forms, including linear, quadratic, cubic, and others.
  • The point-slope form, standard form, and slope-intercept form are the three main types of linear equations.

So, let 'x' be the distance of the 1st part and 'y' be the time in hours of the 1st part.

  • 1st part: 1/4 = x/y (Equation A)
  • 2nd part: 0.8 = 1.9 - x/2 - y (Equation B)

Plot the equations on the graph as follows:

(Refer to the graph attached below)

Be obtain:

  • x = 0.7 miles
  • y = 0.5 hours

Therefore, using equations we now know that the distance of the first part of the Yuna's swim is 0.7 miles.

The complete question is given below:
In training for a triathlon, Yuna swam 1.9 miles in the open ocean, which took her 2 hours. For the first part of her swim, she averaged 1.4 miles per hour. For the second part of her swim, she swam against the current and started to tire, so her average speed decreased to 0.8 mph. What was the distance of the first part of Yuna's swim? Round to the nearest tenth as needed. The distance in the first part of her swim was miles.
