Select the correct answer from each drop-down menu.

Mike and Breanna like to run after swim practice each day. Usually they run the same distance, x miles. Today, however, they ran different distances.

Mike ran at 7 miles per hour and ran 2 more miles than usual.

Breanna ran at 6 miles per hour and ran 1 more mile than usual.

Complete the table to show each person's distance and rate, which could be used to create rational equation relating their distance, rate, and time.

Solución

To complete the table with the given information:

 

  • Mike ran 2 more miles than usual, so his distance is \(x + 2\) miles. His rate is 7 miles per hour.
  • Breanna ran 1 more mile than usual, so her distance is \(x + 1\) miles. Her rate is 6 miles per hour.

 

Supplemental Knowledge

  • In algebra, the relationship between distance, rate (speed), and time can be expressed with the formula:
    \[\text { Distance} = \text { Rate} \times \text { Time} \]
    For this problem:
  • Mike's usual running distance is \(x\) miles. Today, he ran 2 more miles than usual, so his distance is \(x + 2\) miles.
  • Breanna's usual running distance is \(x\) miles. Today, she ran 1 more mile than usual, so her distance is \(x + 1\) miles.
    Their rates are given as:
  • Mike: 7 miles per hour
  • Breanna: 6 miles per hour

 

Theory in Practice

Imagine you and a friend are training together for a marathon; each aiming for different speeds and distances every day. Tracking progress involves understanding how changes to routine (such as adding extra miles or speed-changing) affect overall training time - this knowledge can help optimize schedule and maximize results.
