James and lucas competed in climbing a mountain and coming back. james climbed at an average rate of 3 mph and ran back at 4 mph. lucas climbed at an average rate of 2 mph and ran back at 5 mph. if the path from the bottom to the top of the mountain was 2 miles, how much time did each take to finish and who was faster?

Step-by-step explanation:

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
