Poyasnenie:
Kak dolgo letet' k Solncu ? Semiletnyaya Britani i dvenadcatiletnii D.Dzh. zadumalis' nad etim voprosom odnazhdy posle obeda.
Semiletnii Dzheims predlozhil ispol'zovat' gonochnuyu mashinu. Chetyrehletnii Kristofer s nim byl polnost'yu soglasen. Vzroslyi Dzherri, kotoryi obychno ocenivaet vremya semeinyh
puteshestvii , delya rasstoyanie na skorost', predlozhil sdelat' nekotorye rasschety. "Rasstoyanie do Solnca sostavlyaet 150 millionov
km . Poetomu, esli my budem dvigat'sya so skorost'yu 150 km v chas, nam potrebuetsya 1 million chasov, chtoby dobrat'sya do Solnca". 1 million chasov - kak dolgo eto ?
1 god raven 365 dnyam, t.e. 8760 chasam. 100 let ravno 876 tysyacham chasov - vse eshe men'she milliona chasov. Da, Solnce deistvitel'no nahoditsya ochen'-ochen'
daleko . Kristofer ne byl vpechatlen etimi chislami, odnako, kogda on vyrastet, on poimet. A Vy ponyali, kak eto daleko, 150 millionov km? No dazhe s takogo dalekogo rasstoyaniya
nam prihoditsya shurit'sya, kogda my smotrim na Solnce !
