It would take Lin 36 minutes to ride 6 miles. To answer this you must divide 120 by 20. You'll get the answer 6. This is your unit rate. You then take the unit rate, 6, and multiply it by how many miles she rode. In this case, 6*6. Or if you prefer an equation: (120÷20)*6=36min.

Answer:

4(2qp + 5qr - 4s)

we can use 4 as a common factor between these numbers.

8/4 = 2

20/4 = 5

16/4 = 4

so

4(2qp + 5qr - 4s) is the most factorized answer we can get

Is this correct? I used the 90/360 x 2 π (90)
slavikrds [6]

The circumference is found by multiplying the radius by pi by 2

And then the arc length would be multiplied by the fraction of the circle..

So using what you wrote is correct, but the answer you got is incorrect.

2x 3.14 x 90 = 565.2 meters

565.2 x 90/360 = 141.3 meters
