A toy car is made to travel
different distances, and the time taken to travel each distance is recorded. The results are shown in the table
and also on the graph. Which reading from the table
records the measurements of distance and time that are shown by the pink marker on
the graph?

In this question, we’ve been asked
to match the pink marker on the distance–time graph with the correct reading from
the table. A distance–time graph is made up of
a vertical axis representing distance and a horizontal axis representing time. By studying the graph, we can see
that the total distance on the vertical axis is 50 meters.

Notice that there are five grid
lines on this axis. So each line must represent
one-fifth of the total distance moved. Therefore, each of these grid lines
marks a distance of 10 meters. The horizontal axis tells us that
the total time taken for the toy car to travel is 20 seconds. And again, there are five grid
lines on this axis. So each grid line must represent
one-fifth of the total time taken. That means that each grid line
marks a time of four seconds.

Now, let’s take a look at the pink
marker to find its corresponding distance and time measurements. We can see that along the vertical
axis, the pink marker is on the third grid line, which corresponds to a distance
moved of 30 meters. We can also see that along the
horizontal axis, the pink marker is on the third grid line, which corresponds to a
time taken of 12 seconds.

Now that we’ve worked out the
distance and time represented by the pink marker, we just need to identify which
reading in the table, whether it’s the first, second, third, and so on, records
these measurements. For the correct reading, the value
in the “distance moved” column is 30, and the value in the “time taken” column is
12. Looking at the table, we can see
that the fifth reading matches, with a distance moved of 30 meters and a time taken
of 12 seconds. Therefore, the fifth reading on the
table records the measurements shown by the pink marker on the distance–time
graph.
