Poyasnenie:
Kak dolgo letet' do Solnca? Semiletnyaya Britani i dvenadcatiletnii Dzherri dumali nad etim voprosom odnazhdy vecherom posle uzhina. Semiletnii Dzheims predpolozhil, chto nuzhno ispol'zovat' ochen' bystruyu gonochnuyu mashinu. Eta ideya byla aktivno podderzhana chetyrehletnim Kristoferom. Dzherri umeet vychislyat' vremya, kotoroe trebuetsya dlya ih semeinyh puteshestvii. Dlya etogo on delit rasstoyanie na skorost'. Poetomu oni reshili poschitat'. " Solnce nahoditsya na rasstoyanii 150 millionov km ot Zemli . Esli my budem letet' so skorost'yu 150 km/ch, eto rasstoyanie my preodoleem za million chasov." Million chasov - skol'ko eto? 1 god raven 365 dnyam, umnozhennym na 24 chasa v sutki, - t.e. 8760 chasov. Sto let sostavlyayut 876 tysyach chasov. No dazhe stoletie eto ochen' malen'kii promezhutok vremeni po sravneniyu s millionom chasov. Takim obrazom, Solnce nahoditsya deistvitel'no ochen' i ochen' daleko . Na Kristofera eto ne proizvelo nikakogo vpechatleniya, no, kogda on povzrosleet, on poimet. A Vy ponyali, naskol'ko eto daleko, 150 millionov km? I naskol'ko moshno nashe Solnce, tak chto my dazhe s takogo rasstoyaniya shurimsya, glyadya na nego .
