The graph represents the speed at which Pete’s marble travels. The speed of Stephano’s marble is represented by the equation f = 2.25s, where f is the distance in feet and s is the time in seconds.
Whose marble will reach the 6-foot mark sooner?

B

Step-by-step explanation:

Here, we simply want to know who will reach the 6-foot mark sooner

Mathematically, we need to get the slope from the graph

Looking at the graph, we can see that the 3 ft mark was reached at exactly 2 seconds

So what this mean is that, in 4 seconds, the 6 ft mark will be reached

This makes up the fact that the speed for Pete’s travel is 1.5 ft/ secs

Now compare this with what Stephano has, which is 2.25 ft/ s

we can see that stephano is traveling at a better speed and will reach the 6 ft mark first

So the correct option is B

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

false
