Object 1 travels 5/6 of a foot more per minute than object 2. Thus option (D) is the correct answer.
What is a graph?
"A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner. The points on the graph often represent the relationship between two or more things".
For the given situation,
The graph is plotted between time and distance.
The distance is represented as 'd'
The time is represented as 't'
The speed is represented as 's'
The formula for speed is given as speed = distance/time
Now consider object 1 :
Distance, d = 105 feet
Time, t = 70 minutes
Now consider object 2 :
Distance, d = 70 feet
Time, t = 105 minutes
Take the ratio of their speeds.
[tex]s1:s2 = \frac{105}{70}:\frac{70}{105}[/tex]
⇒ [tex]s1:s2 = \frac{3}{2}:\frac{2}{3}[/tex]
⇒ [tex]s1:s2= \frac{9:4}{5}[/tex]
Hence we can conclude that object 1 travels 5/6 of a foot more per minute than object 2. Thus option (D) is the correct answer.
