Question 1607 in the bank

Which number marks the length of the “rear extension” of the bus in the picture?

Side view of a white bus with a red stripe and two rear axles. Four measuring lines run from the rear end toward the wheels, labelled 93, 75, 78, 82 from top to bottom.
  1. Correct answer: 78
  2. 75
  3. 82
  4. 93

Why this is the answer

The correct answer in the official bank: 78

The rear extension, or rear overhang, is the distance from the rearmost point of the bus to the centre of the rear axle. When there is a tandem, meaning two rear axles close together, it is measured to the midpoint between the two axles, so the answer is 78. Measuring only to the centre of the last axle, marked 75, does not apply to a bus with a tandem axle.
