Jeff hiked for 2 hours and traveled 5 miles. If he continues at the same pace, which equation will show the relationship between

Lady_Fox [76]

Answer: The relationship between distance and time is $d=2.5t$ and the graph is continuous.

Step-by-step explanation:

Since we have given that

Number of hours he hiked = 2 hours

Distance covered = 5 miles

Speed would be

$\dfrac{Distance}{Time}\\\\=\dfrac{5}{2}\\\\=2.5\ mph$

Let the distance be 'd'.

Let the time be 't'.

so, the relation between distance and time would be

$distance=Speed\times time\\\\d=2.5t$

The graph is continuous because it is not based on counts and the points are connected with a continuous line without any break.

Hence, the relationship between distance and time is $d=2.5t$ and the graph is continuous.
