SOLUTION:
120 miles = 60 seconds
120 ÷ 240 = 60 ÷ 240
120 × 1 / 240 = 60 × 1 / 240
120 / 240 miles = 60 / 240 seconds
1 / 2 mile = 1 / 4 seconds
1 / 2 mile = 1 / 4 ÷ 60
1 / 2 mile = 1 / 4 × 1 / 60
1 / 2 mile = 1 / 240 minute
FINAL ANSWER:
Therefore, it will take Rachel 1 / 240 of a minute to swim a 1 / 2 mile.
Hope this helps! :)

The length of the ladder is 34.33 feet if the electrician leans an extension ladder against the outside wall of a house so that it reaches an electric box 33 feet up. The ladder makes an angle of 74° with the ground.
<h3>What is a right-angle triangle?</h3>
It is defined as a triangle in which one angle is 90 degrees and the other two angles are acute angles. In a right-angled triangle, the name of the sides are hypotenuse, perpendicular, and base.
We have:
An electrician leans an extension ladder against the outside wall of a
house so that it reaches an electric box 33 feet up. The ladder makes
an angle of 74° with the ground.
The ladder, wall, and ground makes a right angle triangle.
From the sin ratio;

Here is X is the length of the ladder.
We know sin74 = 0.961
After putting, we will get:
X = 34.329 ≈ 34.33 feet
Thus, the length of the ladder is 34.33 feet if the electrician leans an extension ladder against the outside wall of a house so that it reaches an electric box 33 feet up. The ladder makes an angle of 74° with the ground.
