we need to see the drop down list of steps to answer the question :)
the amount of time of the two trips is a proportional relationship
<h3>What is proportional relationship?</h3>
mathematical expressions are said to be proportional if there unit rate are equal. this means that the expressions will give similar results when similar values are substituted into the equation.
<u>solution:</u>
Driving 7 hrs within 385 miles represents a unit rate of 385 / 7 = 55 miles per hour or 55 mph
while 3 hrs in 165 miles represents a unit rate of 165 / 3 = 55 mph
since both situations gave similar speed in miles per hour they are said to have a proportional relationship.

Step-by-step explanation:
1. radius=13in
diameter= 2r =2(13)=26in
area=πr²= 22/7*(13)²
531.14in²
circumference= 2πr=2*22/7*13
81.71in
2.radius=32ft
diameter= 2r =2(32)=64ft
area=πr²= 22/7*(32)²
3218.28ft²
circumference= 2πr=2*22/7*32
201.14ft

know what is </span>12/39 in
simplest form, you can
calculate this using the following step:<span>
12/39<span> simplifies
to 4/13 (the common factor of 12 and 39 is 3, so you can divide both
numbers by 3).</span>
<span>The
result is 4/13.</span></span></span>
