Question

The Skylon Tower at Niagra Falls has a rotating restaurant at the top of the tower that is circular and has a radius of 54 feet. It makes one rotation per hour.

At 6:42 p.m., a customer takes a seat at a window table. They finish dinner at 8:30 p.m.

a) Through what angle did their position rotate during their stay?

b) How many feet did their position rotate?

Answer 1

1 revolution is 360 degrees

 1 hour = 60 minutes

$360/60 = 6$

 so it rotates 6 degrees every minute

135/6 = 22.5 minutes
