Answer:

1/44×175 + (35 √(3))/44 about 5.3550404151116069380331959534705802918863223609855300450443919154... decimal

Explanation:

To solve this problem, we can use the formula:

time = distance/speed

Where time is the time taken to travel a given distance, distance is the distance traveled, and speed is the speed at which the object is moving.

In this case, the object is moving at a speed of (5-√3) mi/h and needs to travel a distance of 35 mi. Therefore, we have:

time = distance/speed

time = 35 / (5-√3)

To simplify this expression, we can multiply both the numerator and denominator by the conjugate of the denominator, which is (5+√3):

time = 35 / (5-√3) * (5+√3) / (5+√3)

time = 35 * (5+√3) / (25-3)

time = 35 * (5+√3) / 22

Now, we can simplify this expression by multiplying the numerator and denominator by 2:

time = 35 * (5+√3) / 22 * 2 / 2

time = 35 * (5+√3) / 44

Therefore, the object will take 35 * (5+√3) / 44 hours to travel 35 miles at a speed of (5-√3) mi/h.

Expand the following:

(35 (√(3) + 5))/44

35 (√(3) + 5) = 35×5 + 35 √(3):

((35×5 + 35 √(3)))/44

35×5 = 175:

(175 + 35 √(3))/44

(35 √(3) + 175)/44 = 1/44×175 + (35 √(3))/44:

Answer: 1/44×175 + (35 √(3))/44
