How would you explain this You are riding in a car at 80kmh A fly trapped in the car rests on your shoulder Describe the speed of the fly using two different reference points?

In: Science [Edit categories]

Answer:

The fly is motionless, compared to your shoulder or the rear-view mirror.
The fly is traveling at 80 km/hr with reference to the street signs on the side of the road.

Assuming that traffic is going 80 km/hr each way, the fly is traveling at 160 km/hr with respect to the oncoming traffic in the other lane.
