Question

The graph indicates the running route for Tobias.

A graph with horizontal axis time (seconds) and vertical axis position in (meters). The line runs in straight segments from 0 seconds 0 meters to 4 seconds 10 meters to 6 seconds 5 meters to 10 seconds 10 meters to 12 seconds 15 meters to 14 seconds 5 meters to 16 seconds 22 meters to to 20 seconds 28 meters.

Which best describes his run?

From time 0 to 6, he went fast and then slowed down.
From time 6 to 10, he was at his slowest.
From time 12 to 14, he went very slow.
From time 14 to 18, he went toward the starting point.

Answer 1

from 6 to 10 he was at his slowest

Step-by-step explanation:

I took the test

Answer 2

From time 6 to 10, he was at his slowest

Step-by-step explanation:

The speed is indicated by the slope of the line segments on the graph. It is not too difficult to determine the fastest (steepest slope) and slowest (shallowest slope) segments on the graph.

Tobias ran his slowest from 6 seconds to 10 seconds (red segment on the graph).

_____

Slope is computed as "rise"/"run". On this graph, that is ...

(change in position)/(change in time)

You can compute the slopes for each of the segments, but it is easier to look at the graph and make a visual assessment of the slope of a segment relative to the others.
