Question

the table shows the rate of speed at which a glacier is moving
if the slope of the graph remains consistent, how many days will it take for the glacier to move a total distance of 4,500 feet?
15 days
30 days
25 days
45 days

Explanation:

Step1: Find daily distance (slope)

From the graph, at $t=2$ days, distance $d=300$ feet. Slope = $\frac{300}{2}=150$ feet/day.

Step2: Set up distance formula

Let $t$ = days, $d=150t$. We need $d=4500$.

Step3: Solve for $t$

$t=\frac{4500}{150}$

Answer:

30 days
