## Task 1 - 030521

Cosmonaut Valentina Tereshkova orbited the Earth 48 times with the spacecraft "Vostok 6". On average, she needed about 88 minutes for each orbit.

How long did the entire space flight last?
Without considering the start-up and loading time: An orbit takes on average 88 minutes. Thus, 48 orbits require $48 \cdot 88 \mathrm{~min}=4224 \mathrm{~min}=70 \mathrm{~h}$ and $24 \mathrm{~min}$.
