The rate at which Tanya's turtle travels is 0.25mi/hr
This question is from a topic in mathematics called Rate.
<h3>Rate</h3>This is a ratio in which different terms in different units are compared against each other.
In this question, for every 1/6 of an hour, the turtle is crawling 1/24 of mile.
Data given;
- 1/24 miles in 1/6 hour
Let's express this mathematically
What this calculation shows is that the turtle travels at 0.25mi/hr
The rate at which the turtle travels is 0.25 miles in an hour or 0.25mi/hr

The difference in concentration of hydrogen Ions between pH5 and pH6 is - x 10.
The pH scale is a scale or measure to find the strength of acidity or the basic nature of a solution or substance. pH 1 is acidic and pH 14 is the most basic on the scale.
- The concentration of hydrogen ions is inversely related to its pH
- More hydrogen ions present, the lower the pH
- The fewer hydrogen ions, the higher the pH We know,
pH = -log(H+) then,
=> 5 = -log (H+)
=> H+ = (for pH = 5)
=> pH = -log(H+)
=> 6 = -log (H+)
=> H+ = (for pH = 6)
Thus, The substance with the lower pH (5) has 10 times as many hydrogen ions per volume of water.
