A hiker is climbing at a constant rate of 2.4 miles per hour.

Part A

If d represents the distance the hiker climbed and h represents the time in hours, write an equation to model the relationship. Explain your answer.

1 answer

Part A

The equation to model the relationship between distance (d) and time (h) for the hiker climbing at a constant rate of 2.4 miles per hour is:

d = 2.4h

This equation represents the distance the hiker has climbed (d) being equal to their rate of 2.4 miles per hour (the constant) multiplied by the time in hours (h).

Part B

​Time (hours) Distance (miles)​
1 2.4
​1.5 d = 2.4 * 1.5 = 3.6
2 d = 2.4 * 2 = 4.8
​2.5 6.0

Time (hours) Distance (miles)​
1 2.4
1.5 3.6
2 4.8
2.5 6.0

Part C

To find out how much time (h) it would take for the hiker to climb 12 miles, we can use the equation from Part A:

12 = 2.4h

Now, we can solve for h:

h = 12 / 2.4

h = 5

So, it would take the hiker 5 hours to climb 12 miles.
