Question

Two students were asked to plot a distance-time graph for the motion described by Table A and Table B.

Table A
Distance moved (m) 0 10 20 30 40 50
Time (minutes) 0 2 4 6 8 10
Table B
Distance moved (m) 0 5 10 15 20 25
Time (minutes) 0 1 2 3 4 5


The graph given in figure is true for

Options

  • both A and B.

  • A only.

  • B only.

  • neither A nor B.
