Explanation:

a1) Through how many radians does Jamie turn in 99 minutes?

One revolution is equal to 2 * pi radians, so 1.08 revolutions is equal to 1.08 * 2 * pi radians.

In 99 minutes, the restaurant rotates for 99 / 60 = 1.65 hours.

Therefore, the angle Jamie turns through in 99 minutes is 1.65 * 1.08 * 2 * pi radians.

a2) Exact answer:

angle = 1.65 * 1.08 * 2 * pi radians

b1) Approximate answer (rounded to 3 decimal places):

angle = 11.045 radians

b2) How far does Jamie move in 99 minutes?

The distance Jamie moves can be calculated using the formula:

distance = angle * radius

where radius is Jamie's distance from the center of the restaurant, which is 22.2 meters.

b2) Exact answer:

distance = 11.045 * 22.2 meters

b2) Approximate answer (rounded to 1 decimal place):

distance = 245.3 meters
