Пусть х км/ч это скорость автомобиля, тогда из города до посёлка он ехал 3х км,еслибы он ехал со скоростью (х+25) км/ч, то проехал расстояние равное 2(х+25) км. Эти расстояние равны.

3х=2(х+25)

3х= 2х+50

х=50.
3х= 3*50= 150(км)

Ответ:150 км

Queen of Soul

Aretha Franklin, the “queen of soul,” grew up singing in the choir at church. Her father was a preacher and her mother a gospel singer. In her youth, Franklin worked with some of gospel music’s greatest stars, such as Mahalia Jackson and Clara Ward. By the age of 12, Franklin was singing solos. These highlighted the beauty and power of her voice. By the age of 14, Franklin has recorded her first gospel album.

At the age of 18, Franklin moved to New York to pursue her career as a singer. Talent scouts offered her several contracts, and she signed with one of the companies. Franklin made many albums over the next few years, but her talents were not fully expressed. Instead of rhythm and blues, Franklin was performing only pop and jazz.

In 1966, when her contract expired, Franklin signed with another company. Now she was able to focus on her rhythm and blues roots while weaving in gospel and rock. The styles mixed well with her natural talents, and provided a showcase for her soulful voice. Over the next few years, Franklin sold millions of albums. She recorded many hits such as “Respect” and “Chain of Fools”. In 1987 Franklin was inducted into the rock and Roll Hall of Fame. She was the first woman to receive this tribute.
