A car traveled 60km in 45 min. What is the cars average speed in km/hr

Given that,

Distance = 60 km

Time = 45 min

To find,

The average speed of the car.

Solution,

Average speed of an object is equal to the total distance divided by total time taken.

45 min = 0.75 hour

It can be given as :

Therefore, the average speed of the car is 80 km/hr.

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.
