Calculate the average speed and the average velocity of a complete round trip in which the outgoing 72,500 meters is covered at 25 m/s, followed by a 2-hour lunch break, and
the return 72,500 meters is covered at 15 m/s. Express your answer in km/hr.

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.

the awnser is d you right bro
