You are biking at a speed of 18 miles per hour. you are 3 miles behind your friend, who is biking at a speed of 12 miles per hour. write and solve an equation to find the amount of time it takes for you to catch up to your friend.

A. solve by logic:

You bike 18 miles per hour, and your friend, 12 miles per hour.

In one hour, you'd catch up 6 miles, so in half-an-hour you'd catch up 3 miles.

B. Solve by equations:

Let x=time needed in hours

18x-12x=3

6x=3

x=3/6=0.5 hours

definition: a circle is the  set of all points in a plane that are equidistant  from a given  point  called the center of the circle. we use the symbol ⊙ to represent a circle. the a line segment from the center of the circle to  any point  on the circle is a radius of the circle.
