a. at the modern level of technical development?

Note [14]
The Russian source for the problem [MGU 1989] is fully identical to the problem No. 9 in [Soyuz 1989]
Note [15]
In the problems of the Correspondence Round, the time of 50 years was specified [Kvant 1988]: “Astronaut. What maximum travel distance may an astronaut expect in 50 years of flight?” In [Jordens 1989], the problem reads: “Astronaut. What is the maximum distance of space travel during 50 years of flight?”
