Let
x = minutes used for jogging
y = minutes used for handball
z = minutes used for cycling
Th total time spent is 1 hour (60 minutes), therefore
x + y + z = 60
Because Mike jogs as long as he cycles, therefore
x = z
Therefore
2x + y = 60
or
y = 60 - 2x (1)
Jogging consumes 10 calories/min, handball consumes 9 calories/min and cycling consumes 12 calories/min.
The calories consumed in 60 minutes is 580, therefore
10 x + 9y + 12z = 580
Because x = z,
22x + 9y = 580 (2)
Substitute (1) into (2).
22x + 9(60 - 2x) = 580
22x + 540 - 18x = 580
4x = 40
x = 10
y = 60 - 2x = 40
z = x = 10
Answer:
10 minutes of jogging
40 minutes of handball
10 minutes of cycling.

Explanation:
The American Revolution shook the entire world. The thirteen British colonies that would become the United States of America, fought and won the battle against the most powerful imperial power on the planet. In the years that followed the American victory over the British, the hopes of the masses were betrayed. Consequently, there were many popular movements and uprisings. But none had such a great impact on the psychology of the ruling class and the future structure of the US government as the Shays Rebellion of 1786-87, which some have called "The Final Battle of the American Revolution."
Considered the "Father of the Fatherland," George Washington was a celebrated general, farmer, entrepreneur and the first president of the United States.
Alexander Hamilton was an American politician. He was a young lawyer from New York when the War of Independence broke out in the thirteen British colonies of North America (1775-83). In 1777 he became secretary of George Washington, commander in chief of the insurgent army.
