The answer is:
669/221
Discussion:
The ratio of 669 to 221 equals 669/221. Observing the factors, 669 is 3 * 223 and 221 is 13 * 17. As all these factors are distinct primes, nothing cancels in their ratio. Thus, 669/221 remains in its simplest form.
Given:
It is stated that
PQ ⊥ PS and
∠QPR = 7x-9
∠RPS = 4x+22
To find the measure of ∠QPR.
Formula
According to the problem PR sits between PQ and PS,
Consequently,
∠QPR+∠RPS = 90°
Now,
Inserting the values for ∠RPS and ∠QPR yields

or, 
or, 
or, 
or, 
Substituting the value of
into ∠QPR gives us
∠QPR = 
or, ∠QPR = 
So,
The measure of ∠QPR is 40°.

The conclusion is:
The return trip will take 18 hours.
Reasoning:
To determine the duration of the return journey, we must calculate the distance from the destination back to the starting point.
The ship travels at 15 miles per hour (mph) over 6 hours, yielding a distance of:

The distance from the starting point to the destination is 90 miles, and for the return trip, the motor operates at a speed of 5 mph. Thus, computing the time taken gives us:

Consequently, the return trip will take 18 hours to complete.
Have a nice day!
8mm correlates to 2cm just as 8mm aligns with 20mm
The ratio of 8: 20 simplifies down to 2: 5
3.25cm ÷ 5 equals 0.65cm
Multiplying 0.65 by 2 results in 1.3cm
Your answer amounts to 1.3cm
