Question & Answer
Jimmy’s Jogging Distance from Home
1 Answer
Verified archiveThe correct answer is C: 5 miles.
To find out how far Jimmy is from home in a straight line, we can use the Pythagorean theorem. He first ran 3 miles west and then 4 miles north. These two distances form a right triangle, where:
– One leg of the triangle is 3 miles (west).
– The other leg of the triangle is 4 miles (north).
According to the Pythagorean theorem:
( c^2 = a^2 + b^2 )
Where:
– ( c ) is the hypotenuse (the distance from home),
– ( a ) is one leg (3 miles),
– ( b ) is the other leg (4 miles).
Now, substituting the values:
( c^2 = 3^2 + 4^2 )
( c^2 = 9 + 16 )
( c^2 = 25 )
( c = sqrt{25} )
( c = 5 )
So, Jimmy is 5 miles away from home.
