1. A plane travels from Los Angeles to Portland in 2.0 hours. If the distance between the two cities is 960 miles, how fast was the plane traveling? Given Unknown Equation Substitute Solve

480 milies per hours

Explanation:

Step one

Given

time taken = 2 hours

the distance between the cities = 960miles

Required

the speed of the plane

Step two:

the formula for the speed is

speed= distance/time

speed= 960/2

speed= 480 milies per hours

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
