1) d = V*t >>>as you double the av. speed the distance become doubled.
2) after you draw the victors you will find the total displacement = 1 meter to the left.
3) V =d/t =( 8km)/(1.25hr) = 6.4km/hr

Researching the interactions of these phenomena have debunked previous theories around why the lights can have different shapes and can occur in different locations. This research also helps scientists to better understand the interactions between the sun and earth, which could help with predicting space weather.
