Input: Question: How many days passed between Hamilton's first win of the season and his last? Passage:Mercedes won their first World Constructors' Championship after taking a 1–2 finish in Russia. Lewis Hamilton won his second World Drivers' Championship after a season-long battle with teammate Nico Rosberg. Rosberg won the Australian and Monaco Grands Prix, and Hamilton the races in Malaysia, Bahrain, China and Spain after retiring in Australia. The Mercedes team's run of victories ended in Canada where Rosberg and Hamilton were simultaneously hit with a power unit failure that put additional strain on their brakes. Hamilton was forced out of the race and while Rosberg was able to continue, his performance deteriorated and he ultimately finished second. Mercedes returned to the top of the podium in Austria, with Rosberg leading Hamilton across the finish line for his third victory of the season. Hamilton reclaimed ground in the championship standings in Britain winning after Rosberg was forced out with gearbox issues. Rosberg claimed the win in Germany, while Hamilton recovered to third after an accident in qualifying saw him start from twentieth place. Hamilton finished third in Hungary after starting from pit lane, ahead of Rosberg. Rosberg had to settle for second place in Belgium after contact with Hamilton early in the race, which ultimately prompted Mercedes to retire Hamilton's car. Hamilton went on to claim his sixth win of the season in Italy, ahead of Rosberg. Hamilton reclaimed the championship lead with a win in Singapore, while Rosberg was retired with a broken wiring loom. Hamilton claimed the win in rain- and accident-shortened Japan, ahead of Rosberg. Hamilton won the inaugural race in Russia, once again ahead of Rosberg. The result was enough for Mercedes to secure their first World Constructors' Championship. Hamilton took his fifth consecutive win – for the first time in his career – in the United States, again ahead of Rosberg. Rosberg took his fifth win of the season in Brazil, with Hamilton finishing in second. Hamilton carried a seventeen-point advantage into the title-deciding and went on to win the race while Rosberg struggled with electrical problems and finished outside the points. With eleven pole positions to his name, Rosberg won the inaugural FIA Pole Trophy.
