Abicyclist rides his bike each day on a trail not far from his house. during the first part of the ride he is pedaling mostly uphill and his average speed is 6 miles an hour. after a certain point, he is traveling mostly downhill and averages 15 miles per hour. if the total distance he travels is 30 miles and the total time he rides is 4 hours, how long did he ride at each speed?

Examine the paragraph proof. which theorem does it offer proof for? prove jnm – nmi according to the given information in the image. jk | hi while jnm and lnk are vertical angles. jnm and lnk are congruent by the vertical angles theorem. because lnk and nmi are corresponding angles, they are congruent according to the corresponding angles theorem. finally, jnm is congruent to nmi by the transitive property of equality alternate interior angles theorem gorresponding angle theorem vertical angle theorem o same side interior angles theorem
