Answer:

  -12.5%

Step-by-step explanation:

A percentage change is computed using ...

  percent change = ((new amount) -(original amount))/(original amount) × 100%

We want to find the percentage change from 4.8 m, so we have ...

  percent change = (4.2 -4.8)/4.8 × 100% = -.6/4.8×100% = -12.5%

The carpenter made the track 12.5% too short.
