Bergsig lies on the 60°E meridian and Mpumelelo lies on the 30°E meridian. The 30°E meridian is the one South African Standard Time (SAST, $UTC+2$) is set by, so Mpumelelo keeps SAST. When the local time in Bergsig is 11:00 on Tuesday, what is the local time in Mpumelelo? (Every place here keeps the time of its own meridian — there are no half-hour zones and no daylight saving.)
