A fictional table says 12 metres in 8 seconds. Write metres/second and seconds/metre. Choose which rate answers “How long for 3 metres?” and calculate the time under a constant-rate assumption.

Check: 3/2 m/s and 2/3 s/m; time 3 × 2/3 = 2 s. Multiplying 3 m by 3/2 m/s does not produce a time unit.
