Danny runs at a constant rate of speed. At the end of 20 minutes, he has run 2.6 miles. At the end of 45 minutes, he has run 5.85 miles. If n represent the number of miles he has run, in terms of t, the number of minutes he has run, what is his average rate of change?

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.

other answer is correct. i had used the radius of the radius somehow. a website:
