The speed of an object in space is shown in the graph.
Virty [35]

Step-by-step explanation:

the slope is the ratio y/x (or here distance/time) indicating how many units y changes, when x changes a certain amount of units when going from one point to another.

so, we have 2 points here

(0.2, 3)

(0.4, 6)

x (or time) changes by 0.2 units (from 0.2 to 0.4).

y (or distance) changes by 3 units (from 3 to 6).

therefore, the slope is 3/0.2 = 3/(1/5) = 3/1 / 1/5 = 3×5/1×1 = 15

that means based on the graph, that the object travels 15 miles in 1 minute.
