ANSWER

$88 \: inches$

EXPLANATION

The given bicycle has a tyre that is 28 inches in diameter.

How far the bicycle moves forward each time the wheel goes around is the circumference of the bicycle tyre.

This is calculated using the formula:

$C =\pi \: d$

We substitute the diameter and

$\pi = \frac{22}{7}$

$C = \frac{22}{7} \times 28$

This simplifies to

$C =22 \times 4$
