How old is goslo when speedo returns

Reference no: EM13546509

An astronaut (Speedo) travels to a distant planet and back with speed 0.7c. He is 30 yrs old when he departs and 50 years old when he returns. If he has a twin brother (Goslo) who remains behind on earth, how old is Goslo when Speedo returns?
